Just found Firefox's (v149.0) VPN button in my toolbar. I turned it on and entered whatismyipaddress.com. I got the message

"Unable to find the proxy server. Firefox can’t connect to the server at whatismyipaddress.com"

If I turn it off FF brings up the page correctly. I get this error msg for any other urls I try to bring up. Ideas?

I just installed the new built-in VPN - and it appears to show as running in my Mozilla Accounts page (???).

HOWEVER, that is the only place I see it!!

No icon/display panel anywhere (not showing in Customization of toolbar option either) to see usage, turn on/off, etc.??

i have tried to login via your mizilla browser, but not logged in. also when i am trying to browse linkedin and other websites, the web page not opening at first time, i am suffering in problem, but in my laptop i have other 3 browser, chrome, edge, brave, they work correctly and smoothly in the websites and all sites. only problem .

I just got a samsung galaxy s26 (old phone is not available); when i accessed my Firefox, my Collections were missing. From other research, it seems that Collections are not available anymore. However, there must be some way to recover the websites that were stored within them, so i can at least rebuild them.

windoows 102 dressktop with ESET antivirus software. Is firefox running and if YES, how can I turn Firefox VPN OFF or pause it for two or three hours while I update printer software?

It used to be that when entering a search term in the search bar, you could use the arrow keys to select the search engine before pressing enter to make the experience entirely from the keyboard. Now, one must use the mouse to select the engine to be used. It also does not revert to the default search engine after executing the search.

I attempted to set *browser.urlbar.scotchBonnet.enableOverride* to false, and that did not work. I noticed that I had been involuntarily enrolled in an experimental study: Address Bar Update Rollout v1•rollout Address Bar Experience Update which may be the cause of this unwelcome behavior change. If exiting out of that study is possible to restore the previous functionality, please advise how to achieve this.

Please advise how to bring back this work flow efficiency.

(I am not referring to the address bar.)

I've pretty much exhausted my simple little mind about this problem. At some point around the beginning of the year, Firefox changed the fonts on all my toolbars to some ridiculously miniscule font. I've queried Google's AI several times, tried every solution I've received, all to no avail. Is there a way to do this? I just want to enlarge the font in all the toolbars, not the web site contents, and lock it in. Thanks to whoever can help me achieve this.

No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?

после обновления в панели инструментов появилась вкладка профили и она мне даром не нужна но хуже всего что теперь файрфокс каждый раз перед запуском заставляет выбирать профиль и ни какие настройки не помогают! что только не пробовал все бесполезно -- вечно выскакиевает это окно с выбором профиля! какой [edited] мог такое придумать??? и как избавится от эт ого [edited]!!! мне нужен обычный браузер каким он был до версии 150 без [edited] вкладок и [edited] ИИ

Hi everyone,

I’ve been experiencing synchronization issues with Firefox lately.

Current situation: Tabs sync correctly between devices, but bookmarks and passwords no longer sync between my iPhone and my computer.

I’ve also considered an issue with profiles, I currently have three Firefox profiles:

• default-release (currently in use)
• default
• default-release-1

I also used Firefox Troubleshoot Mode (restart with add-ons disabled) to test the issue.

sync-log : The sync-logs show many success-sync entries and only a couple of error-syncs. There are no obvious connection issues (I’m using a shared connection in a rural area). However, bookmarks and passwords are still not syncing properly across devices.

Observed behavior: Sync is active and "functional" Only specific data types (bookmarks and passwords) are affected The issue persists even after signing out and back into Sync, and restarting Firefox on both devices

Checks already done: Sync is enabled for bookmarks and passwords Sync logs mostly show successful operations rather than errors

Hypothesis: A Firefox profile conflict

Question: How can I restore Sync properly without losing my bookmarks, passwords, or other data?

Thank you for your help.

Firefox 150.0.2 (64-bit)

After rebooting my computer, Firefox hangs for a very long time trying to access common websites such as cnn.com, facebook.com, mozilla.org and apnews.com. A google search will work, but the links (including the google control links at the top such "AI Mode All ... More Tools" are not active. Often there is a message at the botton of the screen indicating some external site is being accessed. During this time, other sites that do not have external references will quickly open in other tabs (bwi.com is a good example). After about 20 minutes, everything magically starts working correctly. Disabling "secure DNS" does not correct this problem.

After installing Firefox 150, clicking on a window for a different application does not make that application active. Firefox is not letting me leave! I can switch by going to the sidebar and choosing a different application. None of the other applications exhibit this behavior. MacOS 26.3.1

My microphone does not work properly in Firefox, it sounds periodically really low and that doesnt depend on my mic settings. It seems like that is Automatic Gain Control or something like that and idk how to disable it. On screenshot im just speaking as usual but the browser lowers the volume -_-

Firefox kept losing all of my saved bookmarks and passwords. Each time it updated everything would disappear. I went to the folders where the bookmarks and passwords are stored and the profiles were there but Firefox did not list them when I searched (about:profiles). Tried numerous times to move the files to the current folder but the program still could not see them. Tried copying, moving, changing names of files, etc. Finally uninstalled firefox and attempted a new installation but it will not even open because it says it can't find profiles even though there are profiles in the profile folder. Now what do I do?

I had sync turned on before I reinstalled my OS, and now I have lost everything. Is there anyway to recover the stuff that should be there? Yes or no. If yes please provide steps, and not the self help articles here as they are worthless.

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!
