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 ???

For a while firefox has been having issues where on youtube in particular when tabs are closed they will continue to play audio for a bit after they are closed. More recently I have closed tabs and the audio keeps on going indefinitely after the tab has been closed. This is on the latest firefox (151.0.4 64 bit) on windows 11.

This only seems to happen with youtube and in general youtube playback is buggy, slow, and lags the whole browser taking several seconds to switch tabs to or from a youtube tab or even close it.

In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

Hi Everyone,

I've been having this problem for a wee while when I'm browsing facebook (which works better in Chrome) the site on firefox and as well as messenger is really laggy and I'm wondering if there is a hidden setting that I should change to improve this?

I only have adblock addon installed and I cleaned out the history and browser cookies ect but the problem still remains.

Any ideas? Thanks Rob

I'm experiencing a strange issue with Firefox. Some websites are not loading properly, including my own website, YT Thumbnails. In some cases, pages load partially, while other times they remain stuck loading or display missing content.

I've tried refreshing the pages, clearing the cache, and restarting the browser, but the problem still persists.

Has anyone encountered a similar issue in Firefox? Could this be related to browser settings, DNS, extensions, or network configuration?

Any help would be appreciated. Thanks!

Since Thursday (new update rolled out Wednesday) I have lost all of my open tabs in one window.

Previously, when opening up Firefox, it would reopen my previous window with all tabs.

However now, even with the setting ticked in General (Startup --> Open Previous Windows & Tabs), it no longer does this. I have to go to Menu in the top right, History, recently closed windows, then guess at which window I should reopen.

Will this be fixed in the next update?

I have to reset Firefox/Mozilla as my default browser every time I leave the browser and return. Each time I set it as my default browser, but I have to do it again and again. This is a new occurrence, as I have never had to do this until the last few weeks.

I really need some quality advice and will sincerely appreciate it if someone can guide me, because my head is spinning.

I am trying to access the FoodsCo website, a division of Kroger and I get a page saying that the "authenticity of the received data could not be verified."I cannot go the page at all (screenshot of what I get when I try to access foodsco.net). I checked the same page on Chrome and the page shows up fine and the connection is secure (the website literally has https in it. The S stands for secure). I have tried to add foodsco.net to the exempt list through Enhanced Tracking Protection, but it didn't work. This isn't some dark web site, it's connected to the biggest grocery chain the U.S. I'm very confused here. What is happening?

I am trying to configure our Firefox configuration via Intune and need to use the OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/Preferences with the following JSON:

<enabled/> <data id="JSON" value=' {

 "dom.disable_window_flip": {
       "Value": true,
       "Status": "locked"
     },
   "dom.disable_window_move_resize": {
       "Value": true,
       "Status": "locked"
     },
"network.http.http3.enable": {
       "Value": false,
       "Status": "locked"
 }

}'/>

I do not have any of the Deprecated preference settings in use.

The error presented is -2016281112 and checking the respective settings in about:config on a synchronised device shows that the settings have not applied.

Any help would be appreciated.

Thanks!

Unable to upload camera photos stored on my laptop to Facebook and WhatsApp in last one week . I tested with images that had been successfully posted earlier, but they are also failing now. Interestingly, the very same images can be uploaded without any issue when using Chrome.

Hello Firefox Team

I'm having a problem with Firefox running very slowly, especially when watching YouTube videos. Videos take a long time to load, keep buffering, and sometimes get stuck while playing. The browser also feels slow overall, not just on YouTube. My internet connection seems to be working normally. I have already tried clearing all browsing history, cookies, and cache, but the issue still persists. I'm not sure if the problem is related to Firefox settings, extensions, hardware acceleration, or possibly a hardware issue with my PC.
