While launching Firefox VPN browser all of my bookmarks were erased. Additionally, my backup copy of my bookmark records was also deleted. I have not been able to reboot or restore the system. I need help.

Hello. I have a problem with the chat.deepseek.com website - every time I launch the browser, the language settings are reset from the system (or Russian) language set manually to English. Interestingly, this problem only occurs in Firefox, while other browsers work as expected. Additionally, the test profile created again also works properly. What I have done: 1. Reinstalled the browser, but it did not help 2. Deleted the folders responsible for Local Storage in the profile folder - didn't help 3. Cleared the cookies - helped until the first restart, then it was the same. History is enabled, and cookies are not cleared when the browser is closed. How can I solve this issue without deleting my profile? I don't want to lose my bookmarks, passwords, and website settings. Thank you in advance for your assistance.

When I want to view passwords Firefox is asking windows credentials which I don't have. Now I can't get access. It used to ask for my Firefox password what happened.

I love that you ask us to be nice! I have one bumper sticker on my car and it says: Just Be Nice.

I'm stuck signing into VPN. My email address is shown when I click on VPN in the menu bar but there's no on/off toggle. I click Get Started, it says "Signed in Successfully! Next: Turn on VPN" — but there's no place to do this. It says "Go to the open panel" – what is an open panel? There's an x in a dark circle next to the VPN in the menu bar. It feels like a continuous loop and I'm getting nowhere – that I can tell.

Thanks for your help!

Searches using the provided Amazon search feature found in settings will always have "tag=admarketus-20" in the url. Example: https://www.amazon.com/s?tag=admarketus-20&ref=pd_sl_ [bunch of letters and numbers] &mfadid=adm&k= [search query] Now, if this were an affiliate tag for Mozilla specifically, I would understand, but googling the "admarketus-20" tag turns up posts showing that users on various other browsers (Vivaldi, Opera, Chrome) also reporting seeing this tag popping up in their searches too. I wondered if this was due to malware, but I did a fresh Firefox installation on a newly installed Win10 machine and it happens there too. Who/what is this tag for?

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.

I can open gmail but it does not refresh. If I clear the cache it refreshes the first time only. Sometimes I get a message saying that my account is temporarily unavailable but I can access gmail with no problem on my iPhone, android tablet and with Google Chrome without any problems. Turning off the Advanced Tracking does not resolve the problem.

I've just opened one simple Web site (in addition to Mozilla), and already CPU usage sits at about 20%! Please refer to my recent posts here at "Why is Firefox Suddenly Taking Over my CPU?" for the problem description. I'm re-posting simply in hopes that I can "send data" on this one from outside my sandbox. Regards -- jclarkw

I am not a native English speaker, so I used translation. Please excuse any awkward phrasing. I previously updated my Firefox to version 150, but my tabs kept crashing roughly every 5 minutes. To solve this, I tried installing the Firefox ESR version. However, my profile had already been upgraded to the new version format, so ESR could not read my data. I then reinstalled version 150, but now I'm having profile issues again. I can access and launch my old profile through about:profiles, but I can't seem to save it directly as the default profile. I don't want to have to repeat this process every time I restart the browser. Is there a way to transfer all my data (bookmarks, saved passwords, add-ons, settings, etc.) to a new profile that works with the current version? Or, can I downgrade my profile so that ESR can read it? I have tried copying the files from %APPDATA%\Mozilla\Firefox\Profiles, but it didn't work after many attempts. Please help me. I really don't want to set everything up from scratch again. Thank you!

Hi, I've been trying to permanently allow (instead of the default Temporarily Allow) the Google Voice desktop browser permission to use my microphone and send notifications.

Whenever I open the Google Voice browser in the address bar, there is no option to have Firefox PERMANENTLY allow mic and notifications and REMEMBER THIS DECISION. When I go to into the Firefox settings under Privacy & Security -> Microphone, there are no websites listed in the box in order to allow access.

Is there a way to Permanently Allow the Google Voice website to use my microphone and send notifications and REMEMBER this decision?

Thank you for your advice! Lisa

'bold textHow do I remove the recent browsing button from tab bar. I get shaky hand sometimes and this annoying button messes Firefox up. It is the most annoying new feature ever.

When uploading files with Firefox, I click the upload button, and the file browser window appears to upload files.

For as long as I can remember, it always defaulted to the last folder location that I uploaded a file, but just a few days ago, it stopped working, and always defaults to my home folder.

How can I make the upload window pop up, default to the last uploaded location? My OS is Linux Mint Cinnamon.

the website gem.cbc.ca no longer allows me to play a video in Firefox since Monday this week, but works as usual on Chrome. I have the same add-ons on both browsers Adblock+ and NoScript. Tried in a private window too and all the suggested Firefox settings, no go.

Also I was able to use primewire.mov to watch videos up until yesterday, but none of them will play for me today. Guess I should try Chrome for them too. I use a private window for those sites.

Windows 10PRO + ESU up to date for April Firefox 150.0.2 64bit No other changes except for an Adblock+ update a few days ago.

Hello, when automatic offline backup in stable firefox was first introduced, it worked perfectly fine. It created automatic backups in folder I pointed to. Unfortunately few weeks later it stopped working completely, no idea why. I tried following support article, which is limited to turning backup off, deleting folder and turning it on again. Unfortunately it did not help. As soon as backup starts, it gives me error and does not create any file. It shows "creating backup..." for few seconds, then this banner disappears and only error banner remains.

Can you suggest me advanced troubleshooting for this? Maybe there is some log file which could point me in right direction?

I am wondering if it is some issue with Polish language, because I point to D:\Firefox backup\Restore Firefox but it creates "Przywróć Firefoksa" folder.

Using a Mac Monterey 12.7.6 and uptodate firefox.

Trying to use "tree style tabs". I'm trying to drag and drop a tab named "CHILD" to a tab named "PARENT". Instead of appearing in the tab PARENT the CHILD tab disappears and its content is added to the PARENT tab.

I would prefer the child tab to nest within the parent tab.

Thank you!
