My Thunderbird cache is using a gigabyte of disk space. I'd like to clear it, but it's not clear to me if I would be wiping out stored messages when I do that.

I like to download my emails to my computer (and keep copies on the server, too). I thought that was what I was doing, since I can view my emails when offline, but maybe I'm just accessing the cached copies?

Will I lose my old emails if I clear the cache?

I couldn't sign in to my Ring App and received Incompatible Browser error message. Ring Support told me the new version of their app, which uses my default browser to log only works with Chrome or Samsung Browsers (I've never heard of Samsung Browser). Furthermore, they said I had to delete Firefox from my mobile device in order to get Ring App to work.

This seems ridiculous. What's the problem here please??

I prefer to use Firefox, why do I have so many compatibility issues?

AVG has ended Online Security Add on for Firefox and AVG has told me that I may not be secure when I use Firefox. How can I stay secure on Firefox. I do not want to have to use any other browser.

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

Sir, my hp desktop PC is having -- windows10, Firefox, connect cable Broadband with 100mbps speed, Ethernet, periodically updated. I am very much fond of watching English/Foreign language movies having English CC/Subtitles, online streaming, generally on paid channels e.g. Netflix, prime video, Hotstar, you tube etc. I am not proficient in English language. To read the English CC/subtitles, I have to pause the streaming, read the subtitle and then start the streaming (pause-start, pause-start). After about 15 minutes watching the film, the screen becomes black (no video), with a no signal detected message. But audio/sound remains continue. Then I switch off the PC, restart it, and watch the movie for next 15 minutes., then again black screen.This cycle goes on. But When I watch the film continuously, without pause-start function, then there is no black screen problem. In my opinion this repeated pause-start function causes the black screen problem. Without pause-start function, I cannot watch these movies. I tried some online mentioned solutions without success. Please help me in solving this problem in a simple way as I am not perfect in computer science. Regards.

Hi,

I'm experiencing a problem on Firefox 125 and 126 on Red Hat Linux 8 & 9 and also on Ubuntu 20 and 22 systems.

We have a proxy pac which we have tried loading from an http url, or a local file and both produce the same result.

• Launch Firefox, no access to Internet sites (i.e. no proxy)
• Enter settings and Reload proxy pac
• Proxy works perfectly

Is there any way to force the proxy pac to load on Launch? Why isn't this the default behaviour? or am I doing something wrong?

Thanks

I have thunderbird 115.11.0 (64-bit) on Linux After hitting the test button, I get this error message:

Component returned failure codeL 0x80004005 (NS_ERROR_FAILURE) [nsIFile.createUnique]

Password OK

What does this mean? How do I fix it?

Wanted to sign in to forum.k9mail.app so I could stop asking K-9 Mail questions here. Filled out the "application," but have never received confirmation email back from forum.k9mail.app to allow me to sign in. Re-requested confirmation email 3 times; no reply. Can someone help me?

What address do I need to add to my address book so that replies from this forum don't go right into SPAM/JUNK folders?

The menu bar at the top of Firefox is extremely small. The size is about 1 mm. I have tried all the supposed fixes and none of them work. I have a new Macbook pro using Firefox.

Greetings: Here is an error message that is now so common that I can no longer send email to any account. Also, I have not been able to send email to any gmail account for last year or two. Please help. Error Message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <MattMcKeegan_PLS@proton.me>... Relaying denied: You must check for new mail before sending mail.. Please check the message recipient "MattMcKeegan_PLS@proton.me" and try again."

Thanks. Matt.

Error message 'side by side configuration error'. I've been advised to re-install Thunderbird but not sure if I will lose my many thousands of emails and my address books etc.

this interface uses pop3

When emails are pulled, I can see that it pulls, let's say, 50 messages, the notification shows 25 new messages but the inbox only shows 10. I have looked everywhere for the "missing messages" but don't see them anywhere. I have also had some people tell me that they sent an email response (so they were not entering the email address) and I don't see it.

What could cause these differences?
