Firefox has started redirecting to advertising pages after clicking on a link. Only on 1 site. The site loads but not quite correctly. Normally has information about movie ratings show up when you hover over pictures. Have to double click (double load) to get where you want. Does not do it with Edge. Used to work fine, just started.

I installed the 4 choice AI system and used it once and was impressed. At that very same site I wanted to highlite copy and paste but when I did the highlight was so faint as to be almost invisable . After some attempts and not wanting to lose that feature I deleted the AI via mouse right click. Realizing that was not the problem I have searched several times but cannot get any further thru settings and more tools to try to Reinstall that feature . Also the sparkle button never showed with the fisrt install. It originally appeared of its own accord . Will I get the choice again when I reboot .. ? hope you can help me thanks mike

Losing my mind on this one.

Have 2 Macs I use at home, both running FF 141.0 and Sequoia 15.5.

Use Reader for RSS and Airmail for eMail. Both have settings to allow links clicked in those programs to open browser tabs in background. Handy way of banging through newsletters and RSS feeds before shifting to browser.

One on Mac, that open in battleground setting on both apps works as it has for, oh, last several years. On the other Mac, a few days ago that open in background stopped working with Firefox. It does work properly on Chrome and Safari if I set them as default browser (and, as I mentioned above, on my other Mac).

I've tried resetting Firefox on this Mac using the troubleshooting menu and have also cleared the Firefox cache. I even tried resetting the launch database in that Mac, although the fact Chrome and Safari are working fine suggests the OS isn't the culprit.

I'm unaware of having changed any settings, but am aware that "idiot user" may be the issue.

Regardless of how this happened, any ideas how to sort this annoyance out? Thanks!

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

Hello! I saw that the Test day event had started. In Firefox Beta, I entered messaging-system-action.testday in about:config, put it on a string and set the value to testday as it said in the instructions. When I restarted Firefox, the welcome window did not appear and there was also no letter S next to the search as it should be. Please help!

Thanks for the answers!

My PC died and I could not boot from bootable flash drive.

I had been backing up the system with Acronis to a WD Passport.

I purchased a new computer, and when I did a restore, upon starting Firefox, I did not have my old bookmarks, which are many.

Aren't they stored in a backup? If so, how do I get them back. I'm sure that some of the bookmarks came over from Netscape Navigator.

Thanks,

Bob

There is no longer a 'search tabs' symbol at the top section of the Firefox browser page since I switched to the vertical sidebar for tabs and after searching for help the Mozilla suggestion of ctrl+B just tries to search bookmarks. Please can you help as I have many many tabs always open and use this symbol frequently. Thankyou

Is Webroot a part of Mozilla/Firefox? When Firefox recently updated it began to ask for a Webroot access key and it takes me to this page. I have never signed up for Webroot before.

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

I lost all my personal data on Firefox as soon as I changed the password and I did not know that you can lose everything that I had registered in the download box and the previous archive. Now I am very, very mentally disturbed and I do not feel safe and I am very sad about what happened to me. I am crying now. What should I do? My psyche is really broken due to the lack of information....

I want to know how to go back to the previous page when i hit the back button on the navigation bar instead of going all the way to the original start page, I have trie suggestions like the Backspace ket and the left arrow key but they don't work. would like to know if i can get it to work like it used to.

Thank you

I installed Firefox on my M4 Mac and it was in English, now it's in some other langue and I can't change it back. I deleted it, and reinstalled, same issue.

I cannot get it installed in English and have it remain in English. Please help.

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

While using Facebook, I changed some Meta setting to block ads, then unblocked it. After this, Firefox does not show any Facebook info. Switching to Edge, everything shows as normal. Can't see any setting on the Firefox settings page that controls this.

I have Firefox installed on a Windows 11 desktop. The profile is missing, yet Firefox is working fine, and I see all of my bookmarks, etc.

I have windows set to show hidden files.

When I try to run %APPDATA%\Mozilla\Firefox\Profiles\ it tells me that the location is unavailable.

I cannot find the profile anywhere in file explorer, despite multiple tries to search for it.

If I go to Help > Troubleshooting Information, I see a "Location is not available" message, shown in the attached image.

I could uninstall and reinstall Firefox, but I'd prefer to solve this because the exact same thing is happening to my Thunderbird profile. It doesn't exist anywhere, yet I can see all of my emails and it appears to be working properly. I only found this problem because I wanted to backup my emails but was unable to.

Both of these profiles must exist somewhere, but I've tried everything to find them. Please help me fix this in Firefox, and then if I have a fix here I'll try to apply it to Thunderbird, where I have a lot of emails I'd hate to lose.

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

I have searches from a year (or more) ago that are still popping up and I don't know why. I have done multiple clears of my entire history and individually removed old searches when they pop up - they still keep coming back.
