I discovered, to my dismay, that mobile browsers seem to have a different character limit than desktop browsers for JavaScript prompt() input. How can I work around it to input my long string on mobile? Here's a nice page for testing: https://javascript.info/alert-prompt-confirm#a-simple-page I used printf '%s ' {1..1250} to generate a suitable test string. Please find the resulting 5142-character string below.

On a Mac desktop's Chrome, the website accepts this input, no problem. On Android, it cuts off the input in the middle of 1222, at 5000 characters, and I'm unable to type more. I've tried Brave, DuckDuckGo, Firefox, Chrome, and Opera. The behavior is the same in all these mobile browsers. Changing to the desktop layout in the browser settings has no effect.

I had more than 200 tabs open on opera and they would normally reopen again, even after reboots. My phone broke, but I have a backup of the external SD Card, internal SD Card, and a backup from TWRP which is of a size of 23.7 GB but does not have an obviously accessible structure. Following the advice from [another QA](https://android.stackexchange.com/a/184831/96334) , it is possible to concatenate the data.ext4.win000 to data.ext4.win009 files and access them as a tar archive (It's a good idea to cd to where you want the backup to be extracted to first): >

cat data.ext4.win??? | tar xvfi -

> > What this does is concatenate each file matching the pattern > data.ext4.win??? and then pipe the concatenated files to tar for > extraction. the - as the filename tells tar to extract from stdin. The > i option ignores zero blocks which will be in between each archive > file concatenated. > > In this example I used the ext4 formatted data partition. Change > data.ext4 to match the partition you are extracting. Although the tar command exits with

/data/magisk_backup_bd5d0aa87b96353c78a3bf3a455121d0c767089c/boot.img.gz
tar: Exiting with failure status due to previous errors

it extracts quite a few files before this hapens. However, it is probably better to simply extract each of those files on their own without concatenating them, as in the comment by alecxs: > side note: concatenating win* files is wrong, that files are standalone tarball archives Now that I have my /data directory again, I have access to /data/data/com.opera.browser and /data/app/com.opera.browser-2. What do I do with them to extract a list of urls that were open? ### Directory Structures data/data/com.opera.browser

### System Info I think I was on Android 7.1.1 Rooted with Magisk, but stock ROM ### Recently Closed Tabs Not what I am looking for right now, but I stumbled upon the location of those, in case a future viewer is looking for them:

data/data/com.opera.browser/files/recently_closed_tabs/state-2147481796

### Related Links * [How can I export all my open Firefox Tabs to a text file?](https://android.stackexchange.com/a/205587/96334) is posed about doing so on a living phone, but also points out where the file is located. The relevant file is called sessionstore.js. That does not seem useful for opera. grepping find for "session" only finds shared_prefs/sessionrestore.xml which contains nothing useful for my purposes. * [How can I export the list of open Chrome tabs?](https://android.stackexchange.com/a/104153/96334) ### Promising Files appstate.bin data/data/com.opera.browser/files/appstate.bin contains at least some urls and their titles, separated by a null-byte. strings appstate.bin outputs more than just the urls that were open though. And some of those doubly or not completely. I shall document my journy with this file below. Looking at data/data/com.opera.browser/files/appstate.bin shows that it's a binary data file, but it contains readable strings. Open it with vim appstate.bin or look at hexdump -C appstate.bin.

strings appstate.bin | grep -A3 reader_mode_state

already spits out quite a few urls. But it's not yet obvious to me how the structure of that file actually works. Some entries prefix the url with l or O or K or ] or not at all. In some entries the first line after "reader_mode_state" is the url, in others it is "operaui://startpage" and the url follows further below. But what stands out is that the urls all seem to start with http or https - unless you had some ftp or such open, which I'm pretty confident I did not.

strings appstate.bin | grep http

outputs 1506 lines though. some links are duplicates, others are links I do not care about. e.g. like so:

Since I don't care about duplicates, we can apply uniq to reduce that number down to 967 urls. With sort -u we would get down to 833 instead. But both are still too many. It seems to me like opera also stores the tab's history in there. Removing some obviously unwanted lines gives 523 lines, so ~260 urls:

strings appstate.bin | grep -v -e 'operaui://startpage' -e 'Speed Dial' | grep -A2 reader_mode_state | uniq | grep -v 'reader_mode_state'

As a target number to consider:

strings appstate.bin | grep reader_mode_state | wc -l
231

That means - assuming this target number is a good estimate of how many tabs were open - that I have about thirty urls too many. I think I can live with that.

I'm using Xiaomi Redmi Note 10 Pro (M2101K6G) with Android 13 and MIUI 14. For some reason Opera for Android (Opera browser with AI ) doesn't show up in the standard system Share menu, which is pretty annoying, since launching Opera and manually pasting the URL takes time. Interestingly enough, Opera does show up in the "Open with" dialog for .html files in a file manager. Is it a standard behavior for Opera on Android or is it just me and my device?

I have changed some security settings in my Android yesterday (I don't remember which one). Today most of the pages show "insecure connection" in Opera. I cannot even go to youtubel.com Everything opens as normal in Firefox. I've reinstalled Opera, but the problem remains. How can I undo this?

On this Timeline on Patents.SE , for example, hovering over the S shows it stands for "simultaneous dates" (see image below). This works on Chrome desktop, but not on Opera mobile. [](https://i.sstatic.net/Wy2XA.png)

I'm using Xioami's MI 9 SE phone. I have several PDF viewer apps installed: Mi Doc Viewer, Pdf Viewer Plus, MuPDF viewer... However - whenever I try to open a PDF with one of these, or even with a file manipulation app, from a browser - I either get some error message (e.g. lack of permissions which I can't change, or some blurb in Chinese) - or just an empty screen. Here are two screenshots, of the errors with two apps, when I try to open a file via my (Opera) browser Downloads screen. The file I try to open is desktop.pdf; when pressing it, I'm presented with an app selection dialog, and whichever app I choose, it doesn't work. **With "MI Doc Viewer (Powered by WPS)"**: **With "Document Viewer"**: What might cause this problem, and how can I circumvent or fix it? PS - I don't get this for other file types (at least, not that I've noticed).

AMP creates some issues such as dark mode incompatibility on some websites. How can I disable Google AMP in Google Search on Opera?

Every time I open a page in either Chrome, Opera or Firefox and try to scroll with the tip of my finger, the browser seems to suddenly zoom in and out while scrolling, interpreting the scroll down as a pinch AND scroll gesture. This is f****** annoying. This problem does not occur at all on Android's built-in browser, so I must advise this is not a problem with my touch screen. I experience this issue on my LG Optimus L3, with Android 4.1.2 Jelly Bean. ***EDIT 1***: The problem is probably inherent to the cell phone model, as only I and a friend, who owns an identical phone, have this same problem. ***EDIT 2***: The problem seems to be solved for the last Google Chrome update, but Opera unfortunately still behaves in this way. This means that it isn't a user interaction problem, but a bug.

I don't want to always click on no in those windows: I use a Google Pixel 6 with Android 12.

How can I access the browser console on [Opera Mobile on Android](https://play.google.com/store/apps/details?id=com.opera.browser) ? Browser console = something similar to the developer console window on Chrome, when pressing the keyboard shortcut Ctrl Shift J

Last time, I could simply copy the appstate.bin file to the new device, as described in [this Q&A](https://android.stackexchange.com/questions/225695/how-to-recover-open-opera-tabs-from-backup-data-after-phone-bricked) . But this time, either my backup is too old or something else changed. Copying that file has no visible effect. However, I have synced my open tabs to Opera's servers. On my freshly reinstalled phone, I can still see the "tabs open on a different device" which is that same phone pre-reinstall. I can also view the list of open tabs on www.sync.opera.com/tabs . How can I get all of them open on my phone again? I don't want to manually choose each one until the 1811 tabs are opened. It is also possible for me to view the same list in opera on desktop under opera://activity. I have root access on my phone. ---------- Seeing the number, I'm reconsidering whether I should even bother, since I will probably never look at most of those again. But I'm still curious if there is an easy way of restoring those. The official opera forums [don't sound like that feature exists](https://forums.opera.com/topic/26899/open-all-tabs-from-other-devices) . ---------- When I right-click > save as on the opera sync website, I get the full list in a single line of html (without newlines). Each (I hope) entry is set up like this:

So if we knew how to automatically open the tabs on the phone given the URLs, extracting them should not be too hard.

I have been using Android for the last week. I have Opera for browsing. I download videos from a website directly thru Opera. While downloading it asks me whether to open the video in Opera or default video player of my mobile. Accidentally I once clicked on the "make it default" option and it was directly streamed to the video player. After this it never open in my Opera to download. Because of this I can't download videos into my mobile. If I try to search the name of the video player I cant find it. And please help to restore as it was before.

The problem: I am trying configure my "Opera for Android", the "full" browser for the Android OS, to start at the "Speed Dial", and not at the last loaded website page. This is an issue of saving data traffic. I run a website where some pages are long lists, which I don't want reloaded the next time I start Opera. Yes, I know I could (and do if I remember) close Opera by clicking on the red O, and pick "exit". This works to close all tabs, but I would like to not have to be dependent on my remembering. Any help will be appreciated. I have found no answer for this issue. Usual search results are for everything else other than "Opera for Android". My apologies if I missed an answer somewhere for "Opera for Android". The "Opera Forum" is not usefull, because, again, all answers are not for the Category "Opera for Android". Also, this question is not for Opera-Mini.

I'm using Opera as browser. I can remember that in the past, when I googled a restaurant, I could dial the phone number right from the search results. Now, I see in the title bar tel:, but the dialer doesn't open. In addition, I just noticed that an ebay:// link does also not open the Ebay app but does nothing. Any idea what I have configured for achieving this behavior? And even more interesting: how can I restore the original behavior?

**How to alter android opera lock screen news?** When my android os7 is now unlocked there is the Opera browser lock screen news. How can one alter the content displayed there?

How do I edit the urls of the speed dial buttons in Opera Mobile? For example, I have a url www.economist.com/printedition which redirects to a different url on different occasions. If I use the standard speed dial functionality, I will end up saving the redirected url instead of the printedition url. Is there some file where these urls can be edited?

Recently I found that, enabling off-road mode in Opera mini browser is a great way to hide my browsing data from ISP. So I installed the version 24.0.2254. But I couldn't find the option in enable the off-road mode. Seems like this option is available in old versions but not in latest ones. Is off-road mode is obsolete now or is there any alternative options available?

I have never used Opera. Still, once a day or so I get a notification of some news headline. I don't have to open opera for this, it appears on my phone "dashboard" that lists all my apps and I can also see the notification from the screen that just shows the clock and text message notifications, etc. (Sorry I don't really know much mobile terminology). Is this the same issue described here? https://android.stackexchange.com/questions/149864/how-to-turn-off-opera-mini-discover-top-stories-news-feed The person who posted that question seems to have a problem with the browser home page showing news stories. I'm using Android 6.0.1, Security Patch Level Oct 1, 2016. My phone is a Blu Life One X2. This feature is extremely irritating and I wonder who thought such an intrusive app was a good design decision.

I have two browsers on my device, Chrome and Opera, but generally always want to use Chrome. But even if I select Chrome for opening weblinks and press the "Always" button, it might still ask me again which browser I want to use for some other links. My phone is rooted (it's a Fairphone). Is it possible to just exclude Opera once and for all from being suggested? I only want it to appear when I deliberately start it via the drawer.

Opera Mini has an option to choose between small/medium/large font sizes. I tried to find this option in [the new Opera browser](http://www.opera.com/mobile/android) for Android, but couldn't. Is there any way at all to set the font size for Opera?
