Firefox Community Forum

I am using Firefox as my default browser in Windows 10 Enterprise. Since making it my default, the computer takes forever to start up and often gives me "not responding" messages when trying to open a documents search or other tasks. When I open the Task Manager to stop a stalled task, I noticed that Firefox is using over 3800 mb of memory, more than three times as much as any other browser, resulting in over 70% of my memory being taken up. I am assuming that Firefox is therefore not sleeping or suspending unused tabs. Is this so? If so, is there an add-on or tab manager that will suspend currently unused tabs? I've tried to use the suggested tab managers but found them impossible to figure out. Why don't these add-ons provide instructions on how to set them up?

Thanks for any help or advice you can offer.

Hello,

I have a self-made JavaScript-HTML-Calendar on my local file system. I use JavaScript to change the dom, for example to mark a day in the calender as "holiday" or "work". When I use the "Save as" function of Firefox, Firefox does not save the new version of the dom anymore, it does not overwrite the HTML-file on the disc. It worked fine until mid october 2024, but it seems a recent update changed something.

It still works with other browsers, it is only Firefox i have this problem with.

Does somebody know which setting may have been changed causing this problem?

Thanks in advance

I know this is a minor issue, but after installing Firefox via winget, the search bar in Windows 10 (Windows Search) finds the Firefox app but doesn't display its icon. Is there a known way to fix this?

I often use the Sync function to bring open tabs over from my smartphone to my desktop computer. I have noticed over the past month or so, this functionality has become increasingly unreliable and sometimes does not function at all. At the moment I have no synced tabs showing on my desktop. I have signed out and back in to Mozilla on both my smartphone and desktop multiple times, checked the sync settings, and nothing seems to resolve this. There have been a couple Firefox updates on both the desktop and mobile side, none of which have changed this behavior.

Has anyone else been experiencing this? What other trouble shooting steps can I perform? Any help is much appreciated.

Desktop FF version: v131.0 Mobile FF version (Android): v130.0.1

For years I've used the same email and password to login to Firefox sync. However I discovered in recent weeks my login details are no longer recognised., so am not able to import all my bookmarks and online passwords onto a re-installed operating system. My stored passwords on another system visibly shows the same login details I have always used. This has not happened before, and I did not change my login details, so I am at a loss what has gone wrong.

Any suggestions as to how I can login to syncing.

Hello,

I would like to ask if there is something that can be done to recover bookmarks/logins?

The story: 1. When opening new tab it says it needs restart for a new upgrade. 2. Then nothing happens. When trying opening firefox new window does not load, the process shows for a short time (few seconds) then disappears. When opening it from cmd there is no console log. 3. Then after reading internet, it said that reinstallation could help. I did that, i.e. installed new firefox installator and ran it. After opening, it was a brand new firefox, no bookmarks, login information loaded from existing profile. 4. Tried to recover profile information via sync, but to my unfortunate i reseted the password from mozilla account and login in new mozilla firefox thinking it would fech all the data from server and I could retrieve my history. Unfortunately after the fact I read that it would reset all stored information on that account. 5. Right now in Profiles folder I can see three entries, two of which have only parent.lock file and the other is this brand new profile. I assume/guess it was created during reinstallation.

When going to update history it shows "Install Failed" on Firefox 132 version.

Is this case totally lost and all data is unrecoverable or is there a chance to recover it? When reinstalling, does new installation create a new profile that is futher used or try to use one that was used by already installed Firefox? Has the local profile been overwritten when resetting account password?

I understand that I made few mistakes along the way, e.g. not backing up profiles when upgrade failed, but nevertheless I would like to ask if there is anything that can be done?

Thanks

Hello - I am running Firefox version 132.0 (aarch64) on a mac M1Max running Sonoma 14.6.1. The most recent Firefox update deleted all of my bookmarks and I can't get them back using the Manage Bookmarks->Restore option. I don't have a manual back up file. There were hundreds of bookmarks. Why did you do this and how can I get my bookmarks back?

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

imported my bookmarks from an HTML file but cannot save new bookmarks to the old folders. The folders are there when I look using the 'Show your bookmarks' icon. I can access bookmarks from this icon.

When I try and bookmark a new site the imported bookmark folders do not show up. Help please.

This afternoon, I was browsing and archiving many of my saves, and I frequently received the message that "Something went wrong retrieving your Saves". I have not had this problem before. There's about 6800 articles in my Pocket presently. Am I reaching some kind of limit for maximum articles I can save?

I have already converted my account to login using Mozilla (summer 2023) and I've been using the firefox browser this afternoon.

Would appreciate any insight you could share. Thanks very much.

For about the last month, Firefox crashes regularly, with this message in a pop-up box:

Firefox Crash Reporter Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash. Details: missing field 'include_url' at line 3 column 1

Afterwards, I can re-launch Firefox and resume activities.

Hi there, in my settings in firefox: there is a website that refuses to go away from the "Manage Data" section of the "Cookies and Site Data" section of my Firefox settings. I will select to remove all of the cookies ever, and even when I refresh the settings page, or close and restart the App, or turn my computer off and on again, it is still there. Strange! I would like assistance with this.

of note, I've checked w/ third party extensions that manage cookies, and that website doesn't show up when I manage cookies via said extension.

I have MacOS Big Sur, 11.7.10. I have the latest version of Firefox.

Thank you!

Firefox will not open the website from my email provider, but Vivaldi will. Why? website is: https://webmail.sasktel.net/#/login Firefox 132.0 (64-bit) Windows 10

All I got when trying to drag photos and URLs to my desktop was a red circle-slash. Turns out Firefox is the only browser that insists on UAC being turned on, apparently a -no-deelevate problem — whatever that is. Despite three calls for help here, not a single person read my post. Of course, there's o Mozilla support.

A bigger revelation was that users are not allowed to uninstall Firefox. Requesting uninstall in Control Panel is not an option. Firefox only allows you to initiate a repair. Takes combing through every Mozilla and Firefox entry in App Data and RegEdit to get rid of this pest.

Enough. I've gone from Mozilla to Nozilla.

Hello, I have 3 PCs. One is Windows 10, Firefox 131.0.3 One is Windows 10 firefox 131.0 One is windows 11 firefox 131.0.3

All 3 PCs are running BOINC, using the remaining CPU power up to 100%

On PC W10 + FF 131.0 and PC W11 + FF131.0.3 BOINC and FF share the processor time up to 100% On the PC W10 + FF 131.0.3 when FF is dispatched, no processor time is assigned to BOINC and CPU busy is no more 100%. This situation occurs frequently and can last several minutes.
