Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

I’ve noticed that Firefox consumes a lot of memory, especially when I have multiple tabs open. Sometimes, it slows down my entire system, and Task Manager shows Firefox using over 1GB of RAM even with just a few tabs. Other browsers like Chrome or Edge seem to handle memory better with the same number of tabs.

I’ve tried restarting Firefox, closing unused tabs, and disabling a few extensions, but the problem keeps coming back. I even checked techsquest.com for tips, but I’m still struggling. Are there specific settings, hidden features, or optimizations I can apply to reduce Firefox’s memory usage without sacrificing performance?

Here’s what I’ve already checked:

Firefox is updated to the latest version.

No unusual extensions running (just uBlock Origin and Dark Reader).

Hardware acceleration is enabled.

Any help would be appreciated—thanks in advance!

Since the last update, I believe, because this error occurs constantly and with EVERY video. This is often, not always, the case immediately after updating FF. Now it was fine for a while, but now it's so bad that I'm having trouble watching YT videos properly. Reason: Browser open, logged in to YT. I click on a video to play - video opens, plays maybe 10 to 20 seconds, then playback stops spinning top, I also found out during the last glitch after update that if I switch the resolution briefly, higher or lower doesn't matter - important is to leave the current resolution and switch to another one. And oh wonder - immediately, instantly with the change, the video starts playing. If I wait for this - without doing anything myself, it sometimes takes 30 - 40 seconds for the video to start ... sometimes it just "hangs" ... This is extremely annoying - if it doesn't work, I have to switch browsers... What is also extremely annoying is that it occurs almost regularly after an update ... until the next one possibly, for unknown reasons, does not fix the error, but sometimes mitigates it. Now, however, the disruption/interruption is so massive and totally annoying that I'm thinking of switching. I'm just tired of it ...

When I open a website in Firefox, the page opens OK but there Wikipedia website also opens in the background. The icon appears on the top row to the left of the name of the website I opened. When I close Firefox, the Wikipedia site opens and I have to close that too. Every time. What is going on? How can I get rid of it? Thanks. Windows 11.

I followed your very helpful article and my bookmarks reappeared, but the error message is now showing up every couple of days.

Update: Several days later, this is still happening. I wish someone would please help.

Firefox has been running incredibly slow. I currently only have this window open, but if I open my task manger it shows 10 Firefox windows running. If I right click and end task, it will end the task, but shortly there after a new one will pop up. 1 of the is running in efficiency mode. I assume this is what is slowing down performance, but I do not know how to fix.

I think I am in he correct forum - my apologies of I am "off base" but I am ignorant of computer technology I use an accounting software "reckon" - a programme that originated in America I run firefox as my default browser I run my E mails through G mail

I send invoices from reckon in PDF format attached to an e mail created in Reckon to my clients. Everything ran perfectly (and has done for years) on April 1st. Last week Reckon failed and told me I had the password wrong. (This is rubbish - as nothing has changed) After a week of talking to Reckon help desk I was told that it was Firefox/Gmail who have changed the system and will no longer accept third party interactions. (I think that is what he meant)

Can anyone give me a work round?? Other than printing and scanning and sending manually - I did this yesterday and the time it took was just mind boggling. Many Thanks for any thoughts - as I am not technically minded please be simple in your responses

I don't know how predictive text turned on but it's running in facebook and gmail. Settings in gmail for predictive texting is turned off, but predictive text continues to run.

Using latest version of Firefox on Windows 7 Regions.com login page. Type in user name, click on continue, get error message: "We can’t locate that page right now." "This could be because the system returned an unexpected error or is temporarily unable to process your request. Please try again later."

Many problems with the new Yahoo e-mail. To send an email, I have to close Firefox, open it, and send the email. There are many other issues." Parts of the interface rolling up, for example, it rolls up, and I cannot get to the "to" send space for the address. Across the top of the pane, the "reply, forward, delete icons are not there. If I restart, they sometimes all return. I cannot empty the trash . . . It goes on and on. Thank you. I've been with Firefox for a long time.

Thank You in advance for this great community's help.

How do I clear the offending one half page describing some new pdf function that is covering the right side of the printer control page and cannot be removed. This does not occur in other browsers such as Chrome

I reported a problem here about having an inability to login to Freecycle but had no trouble when using Chrome. I now have a problem with Waitrose.com. I tried to enter the weekend competition but after entering all the data there appeared a message saying something had gone wrong and to try agian later. This I did but the same thing happened. Fortified by my experience using Chrome I tried using it to enter and did so without any problem. I tried turning off enhanced tracking but this had no effect
