I cannot use Firefox without it blowing up my memory to 86GB used in Activity Monitor. I've cleared my cache, closed all my tabs and bookmarked them. I have a Macbook Air M1 2020. I've tried restarting and am definitely using the current version of Firefox. I also updated to the latest OS Tahoe 26.5 to see if that helped. What should I do next please?!

I posted this earlier and the bot named David is trying to take over with ideas that don’t work. How do we stop it? I also posted from my own email and it tried to stop me.

Every time I run Firefox 152.0b10 on Macos Tahoe 26.5.1 Mini it flickers and crashes. Its reporting a webrender compositor error. I made a new installation and it worked but I will have lost all my extensive userChrome/Content customization, as well as hours of time today and more hours to come transferring across and doing things like typing this out and checking versions.

And it flickers awfully on the new installation so is unusable. What should I do? I'm typing this on my Macbook Pro with M3 Pro & Macos Sequoia 15.2, which is not running Tahoe as it bricks all the Adobe software on the laptop. I refuse to rent Photoshop and Premiere for the exhorbitant price Adobe charge, and am transitioning to DaVinci products but not yet done learning.

I have cleared all caches, reset all the hardware acceleration stuff to off or force-disabled, and done everything else suggested by any and every AI agent, like switch off Widevine for a bit then on, or stop UBlock0 running in any way, shape or form. Things change when such things are done but don't work.

This is Ellen. I tried restarting Robert's ( my late husband) computer after it crashed and I got the message about Thunderbird's inbox folder not being able to be opened because it is in use by some other operation. It is an old Mac Mini running 10.13 and it says TB is 115.18.0. I don't update it because I don't think his OS can handle anything newer. I just looked and my Mini with an M1 chip (4 y/o?) is running 140. something.

How do I get it to quit whatever it is hung up on? His email is coming in ok on my iPhone.

Robert was a sculptor who made large kinetic works and a lot of his work is still on this computer.

Please help me get out of this mess. I think it has happened before.

Other than being slow to download my emails now for a few months, TB was performing well until a week or so ago. Now it also won't open the downloaded email when I click on it and the TB freezes up so I can't close it out. I have tried restarting computer multiple times and it works for one or two emails that I can open and then starts freezing up again. Makes using it almost impossible. I have security Windows 11 Defender only and have had it the entire time when it also worked well.

Example: Clicked on a link in a emai from THIS GROUP trying to answer this problem. The responses did not fit so I hit the back button and again got the Fastmail.has stopped working screen.

Has also happened when accessing a site directly through Firefox and the backing up

As I write I am seriously considering walking away from using Firefox and advising all my friends to not use it.

Every time a programme does a update on my desktop, which is several times a week, it crashes Firefox and I get endless messages all day to keep rebooting Firefox.

It is getting extremely aggravating, frustrating and making me very annoyed.

This is supposed to be a modern browser with no big issues, supposedly easier to use than others? not on my desktop it is not and has not been for several months.

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.

So for three days now, my firefox constantly crashes. I would be reading a story online or watching a video on Youtube and then it will suddenly freeze. In videos, it'll still play the sound but the screen will freeze. I can't pause or stop it. Then either Firefox crashes and closes or I have to close it for it to stop. Sometimes, when I try opening it again, it still won't open. I used to have 50 tabs open and never ad this issue. After this, I closed all the open tabs, even deactivated a bunch of extensions, run malware detection, and still the issue continues. I don't know what the problem is. I even followed instructions and deactivated hardware acceleration options in Performance. And I have all AI options turned off too. The app also recently was updated.

I had this trouble after Firefox's previous update, where the browser would just close as I was in a tab. It had stopped so I thought the problem was fixed. However, it just updated the browser a few days ago and again I'm having a problem where the browser will just close in the middle of me entering information. It does not have to do with which program I am in as it just seems to happen randomly. It does not save any information I've typed in.

I have been using Thunderbird for years with no problems. However recently, Thunderbird very often simply stops responding. Sometimes it just hangs up and sometimes the program bar at the top displays "Mozilla Thunderbird (Not Responding)". If I try to wait for it to respond, it literally hangs for several minutes before it begins to respond again, and often, it simply never starts responding again. It has simply gotten to the point where Thunderbird is practically unusable. All my other application software continues to work with no problems. It's just Thumderbird.

The version number in this submission may not be correct. I can't provide the real version number because of the hangups.

Any suggestions?

Thunderbird is very glitchy and slow after the latest update - Thunderbird 140.11.1esr (20260522210329)

Especially, when I get a new email, Thunderbird stops responding for 5-10 seconds and then starts working.

I am using Windows 11

Thunderbird keeps locking up. I have twice uninstalled and reinstalled, yet Thunderbird still locks up with the processing message. At this point, I want to know if 1) there is an online interface that I can try, and 2) If my emails can be salvaged somehow.

I tried the troubleshooting tips on the web, but I can't even get into the folders, even in troubleshooting mode.
