Is there a way to restore a window using less RAM, or if applicable, with regular garbage collection during the process?

While restoring a previously closed window, significantly more RAM is used than when reopening a session, for the same amount of tabs. So if the window ever gets closed and that state saved, I need to revert to a previous session backup. Attempting to restore the window caused ram usage to go up to 30 gigabytes and beyond, at which point I stopped the process out of caution. In contrast reopening the browser with the tabs normally is only about 5 gigabytes.

I regularly use Firefox with thousands of tabs open. This is usually not an issue but in some cases leads to performance issues like these.

For example, when I open a YouTube video on fullscreen, go to the desktop by pressing Win + D, and return to Firefox by pressing Win + D, the video is no longer on fullscreen, but my tabs and taskbar are invisible. It happens on every site with fullscreen, regardless of whether I watch video or play a web game.

I already tried to go into troubleshooting mode, but it did nothing. I also tried to remove fullscreen animation, but nothing again.

How to fix this bug?

I have an old Firefox account/accounts that is no longer used and there have been attempts to access it by someone other than me, I very much would like it deleted and and my data associated with that/those accounts removed, there have been several attempts by someone to gain access to it, i would resolve it myself but i also have no access to it anymore or associated email (mediamonkeysolutions494) and i was forced to create the current account that i am on, which is fine im ok with this, but as for my old account/accounts it needs to go so that i can have peace of mind, if support could contact me I would be grateful. again it is not this account that needs attention, but an old account/accounts no longer used, yes I have had user difficulties with recovering accounts at the time hence is why i created my current one i use

the account to be DELETED IS: mediamonkeysolutions494@gmail.com (FIREFOX)

i am not sure if i have an account with groping.monkey1@gmail.com, (FIREFOX) THAT CAN GO TOO PLEASE

current account i am using to message you is to NOT be deleted

I really appreciate your time and i hope you can be of assistance, thank you in advance

Hello, I accidentally closed all my open Safari browser pages. I opened a new page and went to look in my history, everything was gone and I only have the history for today. There's no yesterday, 7 day ago, last month, etc. Any suggestions on what I may have done? Any suggestions on recovery? Would the tag button have any impact on this? I think I accidentally hit the tag button but I think that was after everything was gone. Thanks

Ref Firefox Ver 84.0.1 OS > Win 7-64 Dear Firefox Support,

 I have already contacted MS support about the subject issue and they were no help.

I am trying to find out what is causing the issue and how to get rid of it.

 I can't be sure but it may be caused by a Microsoft "START" App.  The issue appeared

to begin about two weeks ago, so it's obviously caused by something new, which may be Microsoft related. Below is Dropbox link to a screen capture of the issue.

 Any tips for ridding my PC / Firefox browser of the issue will be greatly appreciated.
 And thank you for the superb browser.

Best regards, Ken Boardman > elsmoko@cox.net

This happens every time I restart Firefox. After "Close all windows" with 4 windows, session restore only restores 3. It seems to be the last window that was opened using "open new window". Off by one error? The tabs that were recently closed in that window aren't in the Recently Closed Tabs either. They do appear in "Show All History".

When I'm using the kayosports.com.au video streaming service website on Firefox (version: 110.0.1) the right arrow button to navigate the media content shelf rows does not register when clicked with the mouse. Previously I was using version 109 of Firefox and the same bug was happening with that version as well.

When using the kayosports.com.au website on other Web Browsers like Brave the right arrow button responses just fine when clicked with the mouse.

I'm using Windows 10 21H2 on Desktop

I have several bookmarks to various craigslist search pages that I visit daily. Last night everything was fine. Today I can't even get there. I get the FireFox error message "Hmm. We're having trouble finding that site. We can't connect to the server https://www.craigslist.org." then the general check network connection etc... This is on my desktop but I can get to it on the cell phone. What gives? I cleared cache and all the normal checks, and have changed nothing in settings at all. I assume if they are blocking me, I could get to the site and be told I was blocked. No reason to block me anyway, so any help appreciated. Oh, I also tuned off all ad blockers and other privacy things running in the background and still nothing.

Clean Windows 11 install, but I have the previous one backed up. Since sync doesn't restore the frequently visited sites on the home page, where can I find the data to copy over myself?

Hey guys!

    I'm running Win 10pro, Microsoft Office Pro Plus 2021 and Firefox X64.  I set Firefox as the default browser, but for some reason that setting isn't "sticking."  If Edge is installed, I can't find it.  Believe me, I tried, because I wanted to uninstall it if possible.

I'm still getting used to the new Outlook (I won't tell you what version I WAS using...) but this is throwing me for a loop...

If I do not have Firefox open: When I open a link in Outlook, a new window is opened in Firefox. This window does not include any toolbars nor are any of my customizations applied (themes, extensions) As a matter of fact, opening the link in this new bare-bones window disables all my extensions and if I want my theme back, I have to remove it from my theme manager and reinstall it, because the option to enable/disable the theme isn't there.

If I DO have Firefox open: When I open a link in Outlook, I get "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." If I close Firefox, I'll get that same bare-bones window and all my extensions and themes are disabled.

Has anyone seen anything like this before and can you help?

Thanks a bunch....

Here exist some problems on my firefox account and I just feel so confused about this.The confusing situation happened yesterday when I install the firefox app on my desktop,I typed in my login email and clicked the enter but the website said that I have to use my main email address to login,I have another email address so I used another email address,about this email address I don't know whether I have used it to create a firefox account,again,I can't login my account,today I directly use the latter email to log in the firefox website,It told me that this email has't been used.So I want to know why I meet this error,and how to solve it.and when I try to change my password,the password-reset email will be sent to both the two email addresses I refeerd to in this question feedback.

Hi, I have recently reset my phone and lost all my Google Authenticator codes. This required me to jump through a lot of hoops to get access back to all of my accounts (I'm still in the process for some accounts). On one occasion, I had backup recovery codes, but they weren't working. I noted that some organisations have the ability to view your recovery key and codes, and others don't. Does Firefox have the ability to do this so that users know that if something happens, they will be able to recover? If not, is this something they can implement?

Kind Regards, M.

In browser settings i've disabled telemetry and data sharing with "mozilla". Why do put mozilla in quotes? Because the data is actually going to google. I'm monitoring my computers connections and i see firefox connecting to google immediately after opening the browser, that's without connecting to any website. Firefox used to be a great privacy browser, these times are long gone and it's a shame. Mozilla, you have lost all honor.

Plus, libraries of firefox are proprietary? Which part exactly? Forks of firefox are most likely affected by the sroprietary libraries aren't they...

My FF updated to 110.0.1 (64-bit) on Ubuntu and several things which use to work really well are now broken.

For example, when making a new account, the password manager pops up asking if you want to save the username/password, but if you mouse over to that popup then as soon as you enter it it just disappears. When logging in somewhere, if there are multiple choices for userid (say with different dates) none can be chosen. You mouse down to the popup with the choices and there's a weird stroboscopic action where the popup disappears and is recreated as fast as it can, over and over, and nothing can actually be clicked on. If you type in the userid then try to enter the password the same thing happens. It's not possible to use the password manager anymore, both fields need to be typed in manually.

Another example is the search field. If you type something and there are several options from previous searches, and you try to mouse down to pick one, the popup disappears. If you click the search keyword again it highlights as for replacement, then you have to click it again (removing highlight) and only then can you mouse down and choose a search engine.

etc etc etc! All this stuff worked great until the upgrade happened (in the background) and now many things are a huge pain in the ass. Arrgh!

I tried disabling all add-ons then restarted but made no difference. Password manager is unusable.

FF 110.0 - Dropdown menu in responsive design mode will not display more than 20 devices, regardless of how many are selected. Does not scroll, as in earlier versions.

Hi all,

I basically have the same question as this one, but I don't understand the chosen solution: https://support.mozilla.org/en-US/questions/1257189

When I installed FF on this laptop, I imported successfully my bookmarks, but for some reason for one particular (large) folder, its bookmarks "Description" field was not imported.

I have both the HTML and the json backup bookmarks files. With the HTML file I can copy and paste individual bookmarks and descriptions, but I have probably over 1,000 bookmarks in this folder.

Thank you.

Having lots of issues with Firefox at the moment, from the browser taking 5 minutes before my home page will even load to this issue which is making me second guess using this browser and i cant seem to find an answer in the help suggestions as im not getting any error codes or anything to point to what is the problem.

When i click on a link - a safe link (even FF states its secure) The new browser tab's link will just constantly cycle loading without loading. Ive tried clearing cache and cookies and it makes no difference.

Ive tried turning off my adblocker and other safety extensions. No difference.

Now yes i am running an old system, but i checked to see if Firefox works on it and it does ( Windows8.1) i started using this as chrome is no longer supported on there.
