Fóram Tacaíochta Firefox

Long time Firefox user here - been on from the start (about 2005), and don't want to switch because I love some features like the Panorama View extension, Context Search extension etc, and it's always been a great browser.

Recently though (not sure if it's just recently, or I've only just noticed), it's so slow. I tried a brand new profile, no extensions, no settings changes, and it's the same. Example loading times:

bbc.co.uk/news Firefox: 14s Edge: 2s chess.com Firefox: 19s Edge: 4s chess.com play vs computer Firefox 38s Edge 2s

https://youtu.be/er9jBysL0vEFirefox vs Edge (YouTube)

So it's not my profile settings or extensions.

BUT, I tried it on a different user profile on the same computer (Switch User from the Windows Start menu), and it's fast!

Why is this, and what do I need to do on my user account to speed Firefox up (keeping my same Firefox profile)?

Thanks in advance.

Pretty much title.

Since about two weeks when I open firefox the browser freezes every few minutes for 10-15 seconds. Launching firefox in Safe Mode or disabling all extensions didn't help. When I open Task Manager during freezes it shows that Firefox is "Not responding" and when I open sub-tasks it's usually one or two causing the problem. When I close those either firefox closes completely or youtube or reddit crashes, leading me to believe it's something with those sites? Refreshing or reinstalling firefox hasn't helped. I'm on Windows 10 (all updates installed) and Firefox 84.0.1 (x64) as of the time writing this.

I hope someone can help and suggest something. I would hate to switch to another browser, but the problem has become unbearable.

Hello, Is this the end of firefox for me? I am a chess fan and download chessgames from this site. I log in on the chessbase site and OK. But suddenly this doesn't work anymore!! Strange because with microsoft edge it works!! Greetings harry

Mozilla Firefox keeps rolling out changes to functionality and the user interface without notification, as well as altering my user preferences. A set of about:config preferences that start with "app.normandy" seem to have something to do with installing these on my Windows 10 system. I did NOT enroll in any FF studies. So, it is odd that there seems to be outside manipulation . I am not a programmer. I would appreciate a lay person explanation.

Every so often when I am browsing and go onto a website the text becomes all jumbled as if it can't read the font properly. This has only started happening recently. It definitely seems to be a font issue as when I copy the text and paste it into a document it reads perfectly and if I close the browser then open it again the text is back to normal. It seems to happen after I've been using the browser for a while.

Hi everyone,

I'm on w7-64. I updated to FF86, and there were obvious problems with it, so I installed 84. Works fine, except that now I'm noticing twitter and facebook get slower over time. I didn't notice that before reinstallation of 84.

I just created a new profile and refreshed. Will monitor. But what is the usual issue when firefox is doing this? Basically its not releasing memory correct?

I tried useing Firemin (https://www.rizonesoft.com/downloads/firemin/), and there was a noticable difference with twitter and firefox. But I'd rather just fix the issue instead of using a bandaid if I can.

During the reinstallation of FF84, I did delete a few registry entries (I followed a page like this to do it (https://www.tenforums.com/browsers-email/164280-remove-firefox-completely-then-reinstall.html)). But I don't know how that could effect releasing memory.

I'll keep you updated, but does anyone have any insight?

Thanks!

I did NOT enroll in any FF studies. Yet, moderator Cor-el said the app.normandy preferences will install new features and 'shield studies' anyways. I stopped downloading FF updates after v.84. I wanted to avoid the disastrous change to the print function that showed up on another computer. I spent hours trying to figure out what happened and how to get rid of of it. Nevertheless, Firefox installed this unwanted print 'update.' So my question is whether it is safe to turn off or delete all the app.normandy preferences in about:config ? Or do I only need to change the settings on a few? If so, which ones. What happens if I change these?
