Firefox consumes a lot of processor time in background. How to disable it?

Following options do nothing: Use recommended performance settings - dasabled Use hardware acceleration when available - disabled browser.tabs.remote.autostart = false

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

When a new bookmark is created it goes to the end of the bookmark listing in the left panel. How can I force Firefox to automatically put each newly created bookmark in the correct alphabetic position in the left panel Bookmarks panel? I DO NOT want to alphabetize the entire panel, I just want each newly created bookmark to go where is alphabetically belongs. I do not use folders so have one long list for bookmarks menu. thank Bob

Hi, I have the problem that Firefox restarts after a crash, re-opening exactly the same windows that were open at the time of the crash, which most of the time reproduces the crash.

I want Firefox to restart with an empty window, like it is configured.

I have read a support entry that hints setting browser.sessionstore.resume_from_crash to false, which does NOT to the job (anymore).

I have to buy a new iMac, which now comes with Sonoma. Is there a version of Firefox that works without major issues on an iMac with Sonoma or is it better to wait? Thanks.

Hello

I hope you can help.

Trying to sync my logins/passwords from my laptop to my desktop. It just doesnt work.

I have reset primary password, logged into both devices, selected sync on both devices. But it does not sync to desktop. Both machines come up in the Connected Services setion of my mozilla account.

When i try to manually enter logins & password on desktop list - it keeps asking me to enter my primary password (despite already being logged into firefox).

This is very frustrating so any help is greatly appreciated.

I have used Firefox with sync since sync were released. Today (25th dec), all of a sudden hundreds of saved passwords are gone, just 9 out of at least 200.

I have changed the password for my account and logged in. Tried to logout and login again but just 9 passwords is found, extremely frustrating!

Anyone got a clue what has happened?

I'm setting up a user on a new computer. I've exported her bookmarks from her old computer. On the new computer I go to Bookmarks > Manage Bookmarks > (select bookmarks toolbar) > Import and Backup > Import bookmarks from HTML. I browse to my folder containing the bookmarks.html file, Open it, and nothing.

I've tried all the suggestions I can find. Places Database Verify Integrity gives me: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane > Task: checkCoherence + The database is coherent etc. Opening the bookmarks.html file shows a list of bookmarks. That file is not empty.

This shouldn't be this hard. How do I accomplish this?

I am once again having issue with Hotmail and Firefox. It's working perfectly fine in Pale Moon, but it's gone totally blank in Firefox. It worked totally fine yesterday, but today I cannot access ANYTHING in Hotmail. Firefox says it's up to date, but usually when I start having issues with Hotmail, it's because Firefox needs to update. Please help fix this problem! All other websites work fine! Thank you!

I'm trying to run Firefox ESR on on a Mac with OS 10.11.6. This page (https://support.mozilla.org/en-US/kb/firefox-mac-osx-users-esr) seems to indicate that Firefox ESR should work on a Mac with 10.11.6, but my computer says that Firefox ESR is not able to run on my Mac with 10.11.6. Any suggestions for how I can get Firefox to run on this older computer?

Hi

I had to change my operating system. before doing that I made sure I have sync my browser. Now after installation browser and login to my account the sync is not doing what I was hoping for. The sync is just uploading the new configuration to the cloud but it is not downloading all the history and add-ons from a version before OS change. I see it is stored but I don't see any option to load those to the current browser. Please, advise what can I do?

My website (onefishfoundation.org) will not load on Firefox. Instead, I get the "Secure Connection Failed" message with the above statement. This just started happening today. My website loads fine It loads with every other browser.

I've tested my certificates on SSLShopper and WhyNoPadlock and there were no issues on either. I've cleared the cache and history on my browser.

I've closed and re-opened the browser.

How do I fix this?

Thanks,

I am trying to print specs for a computer (beck & front) at:

https://www.dell.com/support/manuals/en-us/xps-8960-desktop/xps-8960-setup-and-specifications/back?guid=guid-f2dda353-ba5a-44c0-b85f-6bf1b8c70d15&lang=en-us

The print-out with Firefox captures only half on the picture and relevant info. Luckily, Safari prints correctly. I am wondering why can't Firefox do the job so I do not have to go to Safari for printing? This issue is not specific to this website, it happens often in many other cases. Is this being worked on? Thanks.

I'm using the current Firefox-ESR for Linux x86_64. Under Settings > Privacy and Security > Cookies and Site Data > Manage Exceptions, I blocked http:174.138.51.92 and https:174.138.51.92 several weeks ago. But Manage Data shows 10 cookies last used 45 minutes ago, and Remove Selection for these cookies fails (incidentally retaining the "last used" value), even when repeated multiple times as fast as I can mouse the select, then Remove Selection, then Save Changes then Manage Data .

How can I delete these cookies and site data? And why does it fail for this site and this site only? And how can I block them permanently, short of black-holing that site in /etc/hosts?

Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.

about.ef2a7dd5-93bc-417f-a698-142c3116864f.mozilla This ‘cookie’ (no size shown) has been showing up on my Firefox ‘manage website data’ since at least March ’23 and it will NOT delete. It may not be 'a real cookie' but I still can’t get rid of it.

When I searched online for that apparent address I found: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40175 The info near the top of that site’s page: Torbutton INFO: tor SOCKS: http://expyuzz4wqqyqhjn.onion/static/images/home/png/block-trackers@3x.png?h=70991bcb via --unknown--:cc55771ba6d6e8c6542066863a47e223 SOCKS is a username? And the ‘onion/hidden service’ address cannot be accessed unless using the Tor browser? So that seems a dead end for me.

I have seen 3 other people posting here in the past year about this particular cookie. hobro1 did an uninstall & still had to remove directories manually after getting some answers from several others. blazee decided – based on the answer given by jscher 2000 – that it probably wasn’t dangerous. mekishev 1 received an answer from cor-el that is incomprehensible to me, except for saying ‘it isn’t a real cookie’. I understand it may not 'a real cookie' but then why is it showing up in 'manage website data' where everything else is a cookie?

Can anyone help, please? I’m about to migrate over to a new computer and really don’t want to take this with me. I don’t like the fact that it persists, and that the cookies ‘keeper’ – SOCKS maybe? – is completely hidden.

Thanks much in advance for any assistance!

PS The only possible explanation I've come up with for how it got this cookie is when I was checking out some Firefox extensions; I didn’t even know what Tor was till trying to figure this out.

Hi,

Can I transfer my existing Firefox profile on the Windows 7 machine to a new installation on a new Win10Pro machine by copying the profile from the "AppData" location onto a pen drive, and then copying that into the comparable folder in the new machine.

I assume if I can I will then need to make the copied profile the default one using profile manager?

When I click on a Firefox menu (File, Edit, View, etc.) or the hamburger menu, or a drop-down menu on a web page, the menu appears. Then, when I move the mouse to hover over the menu, the menu vanishes. If, instead, I hold down the mouse button, I can move over the menu without it disappearing.

I'm using a focus-follows-mouse window manager (VTWM) and I think, somehow, Firefox is getting a focus change message when the mouse moves onto the menu. I think this because of the way the Firefox titlebar flickers from showing it's the active window to the inactive window, then active again, once the menu disappears.

Please advise.

Thanks, Richard
