Ho un samsung S21 e da quando Firefox si e' aggiornato alla versione 140.0.3, andando indietro non ci sono piu' le pagine che ho cercato. Vorrei quindi tornare alla versione precedente, e' possibil? Qualcuno mi dice come si fa? Grazie.

I am signed with my email Mozilla Firefox, and I am login but not sync my bookmark and password, plz help me. solve my problem how to recover my old Mozilla Firefox

On the most recent update (7/14/2025), my basic Firefox settings were apparently wiped without any notice. To be clear, other things like my bookmarks were not lost, and my extensions were still installed at least. I previously had Firefox setup to not show me any content when I start it, just a blank page. I also had history saving disabled by default (ie privacy mode). After the update, you started showing me a page that wasn't blank and instead had suggestions on it. Also, the history was being saved from that point on. If I wasn't somewhat tech savvy, I might not have noticed the second change, as there was no warning from Firefox that my settings would be reverted with the update. I eventually figured out how to restore the behavior I had previously with this new version, but it took quite a bit more fiddling than previously to get history saving to be disabled by default when starting Firefox. I do appreciate the addition of fingerprint auth to switch to the app now as an option, but over all this seems like a predatory thing to do to users. I was asked to post here by a developer response to my review on Google Play in which I reported these issues (though much more briefly due to the character limit). I do understand that major updates/changes can require resetting configuration. However, those kinds of updates should display a warning/notice of such a change. I did look for such a notice on the "What's new" content for the update, which isn't something most people would likely even look at, but even there I did not see any indication that past settings would be lost/wiped.

When changing the login password in Firefox, I can select the "Use strong password" option, but the password automatically generated by Firefox will use characters that cannot be used as password (such as symbols), and the system will not accept the "new" password generated by Firefox, so the Firefox's automatic password generation will be wasted. There are very few sites that embed allowed character types as a password on password changing page, so is it possible to manually specify the character type or re-edit the generated password?

Hi!

Just thought I'd report this because it appears to be a consistent, reasonably long-standing issue (months) on a popular news site. Or is it "just me"?

Website: https://www.selfgem.com/en/products/tooth-gem-kits

Expected behaviour: I am able to open links and download files on this website as backround tabs and continue browsing.

Actual behaviour: 1. After a couple are opened, Firefox for Android hangs for very close to 30 seconds then does a deep redraw/repaint of all tabs and continues to function until I next try to open another background tab from that website. 2. During the hang tab interface continues to redraw, but the pages are not repainted and no taps events work. 3. At the end of this hang time, the pages appear to redraw from scratch and the context pop-up for the third long-press appears on top of whichever tab I was looking at.

It is 100% repro for me -- long-press fails when attempting to open the 3rd background tab, but repaint failure occurs earlier. There is something toxic happening.

Curiously, when I next view my Android Home screen, there is some sort deep refresh/repaint, as if it has been swapped-out or GC'd etc.

e.g. Is there some massive memory blow-out happening?

Context/workarounds: 1. I have tried clearing all browsing data and using a guess account on the phone. 2. I have no addons installed. 3. Neither Chrome nor FF Desktop exhibit this behavior. This is FF Android specific

Thanks!

When I use browser for Android mobile phone it simply can not open new tabs for browsing. I have to open some adverts so it could open new tab. In the settings option there is no button or command where I could fix that

I accidentally deleted Firefox Data (Local Storage ) instead of Cache So when I try to login to sites not able to login( Lost all Passwords)But I sync everytime Whenever Password used in Sites (default Sync is On) ,Please Help me to get All my Passwords

I'm using collections in my home page. Great feature, except it's SO EASY to delete something by mistake! There's no Undo, no way to restore what was deleted... It there a way to add more friction for deleting something from there? (An Undo button would also be great but I guess that's more a feature request)

Hi. I realised that a couple weeks ago bookmarks on my Samsung S24 Ultra stopped syncing. Bookmarks added, edited, moved or deleted on the phone since then don't change elsewhere and vice versa. Other devices (two Windows computers) sync just fine. I changed nothing in the settings nor did any other important changes I'm aware of. Passwords, history and tabs sync correctly. I tried going with this on my Android Firefox app: uncheck syncing everything -> log out from Firefox account -> force stop Firefox -> clear app cache -> restart phone -> start Firefox -> log in to Firefox Account -> check syncing everything -> force sync. Didn't help. I didn't clear app data or reinstall the app because I would lose all the bookmarks I added there recently. The only way I see is to look through all the bookmarks in my phone and add them manually on the PC, then reinstall the app - which would be as painstaking as it sounds. I switched to Firefox Beta and it syncs just fine (some minor changes I've noticed compared to the basic app are rather annoying but negligible). Any tips? Cheers, Rafau

I'm using Firefox on Android and I'm having trouble clearing cookies in the following situations:

- When browsing in private mode, after closing all my private tabs and closing Firefox - When browsing in private mode and turning on 'Delete Browsing Data on quit', and quitting by pressing the quit button - When browsing in private mode and manually clearing cookies with 'Delete Browsing Data's

I know cookies haven't been cleared because I'm still logged in to websites in private mode after performing the above actions and restarting Firefox. I need to close and restart Firefox multiple times before cookies are actually cleared.

I have not tried this in regular (non-private) mode.

Could I get help with clearing cookies consistently?
