Forum communautaire Firefox

Gmail won't load or cut and paste, even after rebooting. I deleted firefox and re-loaded it, and that doesn't help.Gmail works on other browsers, but not firefox. Checked for firefox updates, and it is up to date.

I recently switched to Firefox and imported all of my chrome bookmarks. When I open the Bookmarks viewer (Ctrl-B) in the sidebar or the Library ("Manage Bookmarks"/Ctrl-Shift-O), the "Bookmarks Menu" folder contains all of my properly organized bookmarks in a tree of subfolders, just like I expect.

But when I open the "hamburger" menu on the upper-right corner and select Bookmarks, It only shows a list of "Recent Bookmarks" (along with some options to manage bookmarks). I tried using the "Customize Toolbar" feature to add the Bookmarks Menu to the toolbar, but when I open it, it just shows the same thing as if I had gone through the hamburger menu.

I tried looking through Settings, but I couldn't find an option to access my "Bookmarks Menu" from a dropdown menu instead of having to open the sidebar or the Library every time. Is there something I'm missing?

Bonjour. Depuis longtemps j'utilise Firefox Portable dand un bac à sable(SandBoxie-Plus). Depuis la dernière mise à jour Firefox plante, affiche incomplétement ou pas du tout la page. Je signale que sans le bac à sable Firefox fonctionne normalement. Actuellement je suis sur "WATERFOX" portable (version mai 2025) qui a l'air de fonctionner normalement.

I've been trying to get Firefox to save cookies for a few desired websites (bank, investment accounts website, Sync... and of course Firefox/Mozilla itself) so I don't have to constantly use the 2FAs for those accounts. Firefox refuses to keep me logged in to my Mozilla/Firefox account. Every few hours -- or at the very least, after a machine shut-down -- I have to re-login if I re-start Firefox.

I do not use the Firefox Password Manager; it's unchecked in Settings. Nor do I use the Autofill options in Settings. I use the Bitwarden Extension (set to Never for locking/logout -- because this is a home computer) for Firefox to log in to my sites, with a separate authenticator app, Authy.

The Firefox Privacy & Security Settings for tracking cookie blocking are the Standard ones; I haven't done anything to customize them. Further down on that page, I've tried leaving the box blank for clearing cookies on exit. I've tried checking the box and setting up exceptions for those few sites I'd like to login to without having to go through the 2FA rigamarole. I've done multiple Refreshes, clearing of History, uninstall/reinstalls including deletion of every Firefox profile and anything hinting at a connection to Mozilla or Firefox in all Users on the computer, including all the AppData folders. A few days ago, I even deleted the Mozilla/Firefox account and set up a new one with a different email address.

Nothing seems to work. Most recently, Firefox still had all the relevant cookies after the computer was shut down overnight, but an hour into my day's work, after closing Firefox and re-opening it a short while later, all the cookies are gone once again!

None of this was an issue about three months ago. I could save the desired cookies, get rid of other ones, use private browsing, etc. etc., with basically the same set-up and with the Mozilla/Firefox account I had had for years. Now, I've had to delete that account in an apparently vain effort to try to clear out anything "Mozilla" from this computer -- and it didn't work anyhow.

(I posted about this same issue a week or so ago, but didn't receive any responses and have now deleted that Mozilla/Firefox account -- see above -- so this message is an update.)

Long story here:

A few weeks ago, I lost internet connectivity on my desktop PC at work running Windows 11. I checked Firefox, Edge & Chrome but couldn't access any site. It took a few hours and a lot of updating Windows, rebooting each time the internet kicked out, but I got it to work again.

Fast forward to this past Monday the 29th when the issue happened again. Within roughly a minute, the internet just died on my desktop again. I grabbed my work laptop, also running Windows 11: same issue happened within 60 seconds. I checked Firefox on a desktop running Windows 10 - had no issues at all.

Today, I installed Firefox on another laptop (the same model at the other one) running Windows 11. As soon as it synced my account, the internet stopped working. I though it may be the Sync option, so I reinstalled Firefox on my laptop but did not log in to Sync - the same issue: dead internet within 30 seconds now.

I have:

• Run anti-virus
• Run network diagnostics and reset
• Rebooted a multitude of times
• Uninstalled, reinstalled at least twice
• Run troubleshooting in Firefox (which I cannot attach the logs due to it being uninstalled right now)
• Checked to make sure my modem/routers are working right (no one else in the building has this issue and we all use Firefox, but none are synced to my account)
• I even asked my company's tech team (who are mostly software developers) and they said No, sorry, we don't help with that (wonderful right?)

I've attached a screenshot of the OG machine's information. Not sure if it will help at all, but it's worth a shot.

Good morning, Woke up, noticed my screen on (was in sleep mode), guessed PC had restarted itself overnight, that happens, opened Firefox, click sandwich Click History "Recently closed tabs" and "Recently closed windows" are not options I can click...

what the heck please help! I'm going back to bed....

99% of the time, site's work just fine with strict cross-domain referral policies. Sometimes they don't. I don't want to change my browser-wide setting everytime I use ONE site. Is there anyway to add a site-specific exception for referrers?

Sehr geehrte Damen und Herren, ich habe neulich bei GMX einen neuen E-Mail-Account eingerichtet, der auch innerhalb GMX problemlos funktioniert. Bei der Integration in das Programm Thunderbird gibt es jedoch Schwierigkeiten, obwohl ich sämtliche Serverparameter korrekt angegeben habe. Ich konnte den E-Mail-Account nicht einrichten (s. Bild im Anhang). Was habe ich falsch gemacht? Mit freundlichen Grüßen Klaus Reißig

Hi,

When i switch between two tabs by clicking with my external mouse ( I am on one tab and then point and click on another) and then directly start to scroll the page zoom like it does when i hold ctrl+zoom. What causes this?

It does not do the same in other browsers or other apps. It does the same with external mouse and track pad.

Win 11 Pro Firefox 143.0.3 (64-bit)

I'm using version 143.0.1 (aarch64) on macos 15.6.1 (24G90). Ever since I updated to 143, many web sites no longer work.

For example, I get a completely blank page at https://banking.dkb.de/ - see source below.

At https://outlook.office.com/mail/inbox I get an error page - see below.

Here is another example of a blank page: https://www.aircanada.com/home/de/de/aco/flights.

Moreover, the inspector is completely blank for _all_ pages.

The abve pages work fine in Safari. I have used FF for ever since the first release, but am considering ditching it now. I can't find anything about this problem googling.

Please help!!!

When I turned on my computer this morning, and opened Firefox, it froze, and had to be process-ended by Windows.

Subsequently, it also caused Windows Explorer crash.

I was forced to hard-reboot my computer, and restarted it to find all my tabs gone and unrecoverable, and all cookies deleted.

However, my browsing history remains.

Furthermore, my attempt at recovery of this data via the automated backup taken Monday 29 September 2025 - three days before this post - accomplished nothing.

I have looked in several places here, and found no help at all in recovering lost tabs. All threads remain unresolved.

Please provide troubleshooting assistance ASAP.

(And please be aware that the software had to be opened in order to post this question.)

When using "about:support" on Firefox I'm not seeing my "profile path". Are there instructions on this method to make sure I don't loose all of my OneTab-tabs, or should I use another method? A FF comment: If you have a backup of this profile folder than you can restore your data...where do I find this folder?

You also suggest using a backup program--not sure what this means. How do I run backup software on my computer to restore my Firefox profile folder (a file path) ? I do have an external hard drive continuously backing up my files, however I don't know if this will back up browser settings/data whether it does or not- do I need to search for doing this from the manufacturer or from you.

Another suggestion from your help articles: If you don't use our "backup/sync feature, then the only way to recover the deleted data is if (a repeat of the above suggestion )you run backup software on your computer that can restore your Firefox profile folder.

I'm confused on what the backup/sync feature is referring to, unless you're talking (install FF on my Chromebook" so that it puts all my settings and data onto that device? ...sorry.

My problem is Microsoft is giving ppl until Oct 13th (2 weeks away) to upgrade to windows 11. I'm afraid I'll lose all of the FF windows and tabs that I moved into OneTab. This was hundreds of hours of work not to mention the amount of money I've paid to access these websites for research.

Any response would be greatly appreciated...I saw a comment that FF is working on a solution for this but I may not get it until it's to late.

~~Sharp63 (LOL I'm now 78)

OMG..I just saw and update available for FF. Based on what I just read, it's possible I'll lose all of the data in OneTab, What should I do...thinking! First thing is I'll look to see what the update is about, then decide.
