Several months ago, both my Firefox and my Thunderbird stopped working. Thanks to help from this website, both were repaired. New problems have occurred and I’m here again, hoping for help. My computer is a Dell XPS desktop, running Windows 11 (Home), upgraded from Windows 10. Both FF and TB are up to date.

So, problems: TB: I turn on the computer in the morning, have a small breakfast, then start TB. The Inbox appears on the screen and then the request for my password. When I type the first letter, it doesn’t appear. I type it again, it appears, and then I finish entering the password. Works fine after that. Well, almost. I want to delete several non-consecutive emails. What used to work was to hold down Ctrl key, then click on emails to be deleted, finally release Ctrl. Now what happens is the first email to be deleted is highlighted but when I click on the second email, the first email is unselected. Then I release Ctrl, press it once again, select first email, then additional emails to be deleted. They are all highlighted. FF: Inconsistent download times. I just tried to download a webpage from one of my bookmark folders. After about 30 seconds, with nothing showing, I closed the page, then tried downloading again. Another 30 seconds, same result. I closed FF then reopened it, tried loading the same page. It appeared in just a few seconds. Opened the Google webpage, clicked Maps and received the error shown. (First image) Clicked Try Again, Maps reappeared.

Sometime after these problems began, I noticed something different on my Task Bar. When FF was not running and I hovered the pointer over the FF icon, the name of the icon was displayed but was followed by the number 2 within parentheses. (See the image). The same thing for TB. Are these numbers somehow connected to the problems I am having with TB and FF?

Any help will be appreciated. Thanks.

My browsing history in Firefox on mac is incomplete. It used to show complete history, every site, and now only shows a few. How can I fix this to show all history?

For YEARS now firefox has had a massive memory leak that continually eats up more and more of your ram until it inevitably consumes all of it and theres nothing left for windows crashing the PC. Even on startup it uses a disproportionately large amount of ram compared to any other web browser at 2.5 gigs, but it only crawls up from there, and if you leave it running for more than 24 hours your computer will start to stutter and slow to a crawl until it consumes all 32 gigs and crashes the computer unless you regularly restart firefox. And dont give me that unused ram is wasted ram crap, I need that ram to run other programs, 32gigs of ram being used to display one web page preventing me from running any other program on my computer and hindering the operation of the os is wasted ram! I can open up the same session on chrome and use less than a gig. And dont give me the lame ass check the firefox task manager solution either, because firefox's task manager gives you no information, it just says that a single tab is using a ridiculous amount of memory with no details. all my extensions together use less than a gigabyte, HOW HAS THIS BEEN A PROBLEM FOR SO LONG, AND WHY DO YOU REFUSE TO ACKNOWLEDGE IT? There are countless forum posts asking for help with this very issue here and all over the internet.

How do I stop YAHOO from overriding Google when I do a search.? I choose Google as my search preference and remove "browse" but YAHOO keeps popping up at times.

Unable to "Manage bookmarks". If I drag and drop a bookmark into a folder in "Library", and then delete it from where they are saved in Book Marks Current Tab, they are also deleted in the folder. they used to go into "Bookmarks Menu" where I could then re order them into my folders under "Other Bookmarks". Any attempt now to sort them and they get deleted from the folder as well as from "Recent Bookmarks". Will I have to find another way to save bookmarks? Desktop? I have iMac with Ventura 13.7.7. Also, provide answer as to how I can access your answer. [edited email from public support forum]

I've had increasing issues with Firefox performance over the past month or so. I kept hoping an update might fix things but it's getting to the point I need to use Chrome much of the time now. I read the help article for websites not opening with Firefox but opening with another browser and had already done most of the things: clearing data and cache. I don't know what proxy is but I looked at my Chrome settings and changed Firefox to match (automatically detect settings). Nothing has helped. Sometimes a site won't open and sometimes I get into a website and then a random page within the website won't open. I have only a few pages open at a time. It might have started at some point after adding Facebook container to the extensions. Other extensions are: Duck Duck Go, Malwarebytes, Google Analytics opt-out, Read Aloud and U-Block Origin. Any help appreciated. LC

In my Windows 10 PC, I had 1 browser window, with all financial accounts bookmarked on the Fire Bookmarks Toolbar. This window had the extra security tab on the side that I believe added an extra layer of security around activities on those sites.

Windows (11) forced me to purchase a new computer...

Now I'm not sure how to set that up in this latest Firefox and Windows 11. If I select that secure level described here that warns it could cause breaks in activities on some sites, is that the same protection? Will it serve that purpose and can I again only have that level of protection on that one browser window, saving it apart from the main Firefox icon?

Please know any answer will need some plain English - I'm not up to date on computer terminology after 18 years away from my days of understanding. (Windows 3.11 - 7 experience)

Thank you for reading this. Hope someone can point me in the right direction!

I have an account with Songsterr. It's a music tabs site.

I moved over to Firefox as my primary browser relatively recently & I've noticed that the captions in Songsterr are all messed up. I've been on to Songsterr about it & they cannot solve it but, on a whim, I checked Songsterr in Safari & everything appears normal so I'm going to assume for the moment that this is a firefox related issue.

I've added 4 screenshots. The first two are from Safari & show how the captions should appear. The second two are from Firefox & you can see that it's all messed up.

I found an article on Reddit that may be related but I wanted to check here first & see if any of you could shed any light.

Thanks. :)

Here's the Reddit link: link text

No bookmarks show in "All Bookmarks" or anywhere else anymore. The Bookmarks tab only shows a small portion, and when you go to "Manage Bookmarks" they all disappear. Settings? There does not seem to be any instructions as to how to access them and put them in folders like I used to be able to do. IMac with Ventura 13.7.7

i have a big problem with settings of privacy and security. the problem is i cant edit this option ( Allow Firefox to automatically trust third-party root certificates you install ) and its greyed out . i made everything ( refresh - troubleshoot - uninstall ) and with the first click on singing my account on Firefox and add my restore my add-ons after setting up windows this option become unavailable (greyed out) and cant edit it. i need a solution without going to set up a new windows because its so tiring to set up a new windows to edit this option. please give me a solution its emergency. thanks a lot.

After upgrading to Windows 11 I noticed that emoji characters are causing text lines to become blurred or bold on websites, also in developer tools. This never used to happen on Windows 10. Is there any way to fix this?

I am using Firefox 142.0 Note I have also disabled 'Smooth edges of screen fonts' in Windows performance options and display scale is at 100%.
