I have made all restarts etc. No luck. Any help out there?

I am just wondering why FireFox occasionally becomes slow to load web pages. On these occasions, restarting Firefox fixes the problem immediately.

Example, I was just loading the same page repeatedly because of some work I am doing. After about 15 minutes of slow response times, I restarted FireFox and immediately, the page loaded very quickly as usual.

You can see the page where this was occurring at this url: https://legacy-systems.biz/demo/demo.html

Any information etc. would be appreciated immensely.

Okay, so, quick question - I just got a new computer and installed the entire OS (MacOS) directly from my physical backup on . However, Firefox is working quite poorly. It's not loading sites properly, e.g. Facebook, and it won't load pictures on a Danish sales platform - and quite a few other places - most importantly it won't load Tinder profiles to swipe in desktop version. Damn it all to hell!

Also, several of the tabs have a weird, white line under them, and it started blinking with this weird red line in the very top of the browser.

However, if I were to reinstall Firefox altogether, would that delete all my open tabs (of which I have a couple of hundreds)? As per advice from a few geeks, I cleared my entire history to see if it made a difference - alas, the problems continued and multiplied.

If reinstalling and/or refreshing the browser will delete all my tabs - what are my options?

I have added photos to my top sites on Firefox, but everytime I close my browser the images go away and cannot be added again unless I reset Firefox. (The images for the default top sites are still available though.) How do I fix this?

I don't want to have to reconfigure my settings every time the pictures are gone. It seems silly but it just looks wrong to me and I like seeing the pictures so that I know at a glance which top site is which. How can I fix this problem of my browser not displaying the images in the top sites correctly after closing the browser? Thank you!

Firefox on MacOS Catalina fails to save/restore tabs, whether pinned or otherwise, after shutdown.

I have extensions: Bitwarden DuckDuckGo Privacy Amazon smile sponsor redirect Amazon Unsponsored YouTube Sponsor block

Tried it with and without these running and FF fails to save my tabs, regardless of shutting down the browser or the OS. This does not occur on Win10 or my Linux distros. I've been trawling forums and help pages and the Interweb casually for weeks now, without success, but getting quite frustrated now; so posting this as a last resort. Thanks in advance of any suggestions.

Since the last update, I am receiving the error message SSL_ERROR_BAD_MAC_ALERT when I access one website that I need to use as part of my work.

It is a trusted site that I have used for many years. The error message above displays and I get the option to retry which usually works, but I lose any content up to that point.

I have contacted the website owners as suggested and they say it is a Mozilla issue. I found a couple of suggestions to fix this on-line, but it did not work.

Can you help?

Hello! I want to start using firefox instead of chrome, but there is a strange problem — i can't copy. Command+C doesn't work, I can do it only by right click or if I choose "copy" from "edit" in menu bar. But of course i used to command+C. Everything good with other shortcuts. What could be the problem?
