Firefox Community Forum

I suppose this is a kind of support question, of sorts, but in my opinion this also has to be treated as a complaint, in a sense.

About one and a half months ago, Firefox became unresponsive, that is, it became awfully slow. I experienced just about every issue with the browser that was mentioned in the following support pages and support issues (posted by others) and I read all of those :

Websites don't load - troubleshoot and fix error messages

https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors#w_the-problem-only-happens-with-certain-websites

firefox is extremely slow or fails to load sites

Secure connection and security warning error pages in Firefox https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect

An oddball situation had occurred in which I couldn't for the likes of me go to my librarything.com homepage at each restart of the previous Firefox session, which also causes lagging when the session wants to connect to the other (normally unproblematic) website session tabs, and I also get multiple connection errors + insecure connection notifications for some of these websites. (sometimes refreshing a page does not help, sometimes it does)

I got bored reading all those support pages and trying out the solutions, because nothing seemed to help. In the long run, I decided to de-install the whole browser after backing up bookmarks, speeddial settings, passwords and the whole profile. Simultaneously, I also tested the connectivity to these websites in another browser (Brave) and this did not present me with any problem.

So I did the following :

1) deleted the whole cache and closed the browser 2) uninstalled FF with Revo Uninstaller (which has an option to remove all remnant files / folders/ registry items on the Hard Drive) 3) made sure to remove all cached leftovers from HD by using multiple cleanup tools in succession : 1) Wise Disk Cleaner followed by 2) Bleachbit followed by 3) CCleaner

Went to the mozilla website, downloaded and installed the last version of FF. Next, imported bookmarks, speeddial settings and passwords. Next, reinstalled the Firefox extensions I used before (without any lag until one and a half months ago). I also did NOT copy the stored profile but decided on starting afresh with a new profile.

Everything worked lightning fast and efficiently until a few days ago, when I received an automatic update of Firefox - 151.0.3 - and all of a sudden, the same problems are reoccurring. And again, I can't connect to an unproblematic website like librarything.com, whereas before the update I was able to without any problem !!!

What the hell is going on with these auto-updates ???

I still have windows 7 pro on my computer and now I keep getting "Access Denied" from some websites Can your ESL be used on my computer so that I can access my bank; stores, etc.?

I have sound in Windows, but YouTube is dead quit. I have tried all that is suggested in Firefox help and some YouTube sites. Nothing worked. I have tried off the computer and restarted, but no change. My system is Windows 11, sound works, and the latest Firefox update installed. Question is this a YouTube tacit to stop NoScript and uBlock?

wie geht das ?

Hey all. I am having some connection issues with my secondary comp. Firefox 132.0.2

I recently moved and am getting my home office set back up. Nothing was changed during the move other than shutting down, unhooking everything and setting it back up at the new home. My secondary comp is used for live streaming various TV channels, Youtube, live radio broadcasts etc. Youtube, Google and Gmail loads and works fine. Several of the TV channels load the page but will not stream. Rumble, the two radio stations I listen to and our website host access page all give me the Server Not Found screen. It also fails to update Firefox. Also, my Thunderbird will not download new emails. Now here is the weird part. I can go to all of these sites on my main comp and everything loads and works fine. Any ideas? I have tried changing different settings but nothing makes any difference. I even disabled the firewall.

Thanks.

Hi,

I’m using the latest version of Firefox on Windows 11 (currently v126.0), and I’ve noticed a recurring issue: the browser freezes for a few seconds when I switch between tabs, especially if one of the tabs contains a media-heavy website (like YouTube or online editors).

The browser doesn’t crash, but becomes unresponsive for 5–10 seconds before catching up. Task Manager shows a CPU spike during the freeze. I’ve tried the following:

-Clearing cache -Disabling all extensions -Running in Troubleshoot Mode -Updating graphics drivers

None of these solved the issue.

Is this a known problem? Any suggestions on how to fix or further debug it?

Thanks in advance!

I'm on Windows 10. When I try to open the browser, it loads for a second and attempts to open but then crashes and nothing happens. A message box does appear for a second, but it disappears before I can read what it says. I refreshed Firefox and uninstalled and reinstalled the browser, but it is still happening. Firefox works fine on my phone still, so I don't believe it is a problem with my account. I'm also currently doing a virus scan, but it hasn't finished at time of writing.

An error occurred during a connection to lankafriends.com. Peer reports it experienced an internal error.

Error code: SSL_ERROR_INTERNAL_ERROR_ALERT

can not resolve repeated problem : "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Cánt not find "Refresh"

Recently I'm having an issue with Firefox that makes it so when I try to open it, it simply refuses to do so. Say on my desktop I double click the icon it will open for a split second and then instantly close and refuse to do anything afterwards. This is very frustrating, and I haven't yet discovered a solution and would really like to be able to use Firefox again. What is really strange is that this is a persistent problem not only on my laptop but at my pc as well which are two separate devices. If anybody can help or has experience with this problem to offer incite it would deeply be appreciated.

First of all, if you really want to help people, then offer phone or at least chat support -- not bots!

Second, I just uninstalled Firefox for the second time because of problems with connectivity and installing bookmarks

The first time was a problem with the bookmarks and again I had a problem, not with installing them but installing too many -- each imported bookmark installed seven times!

Also, I was having problems loading pages.

You really think people want to spend days rummaging through FAQs to find an answer? You need to provide some good support if you want to survive.

Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox
