I've noticed that Firefox has been running very slowly on my computer recently. Pages take a long time to load, and the browser often freezes or becomes unresponsive. I've already tried clearing the cache and disabling extensions, but the problem persists. I'm using the latest version of Firefox on Windows 10. Are there any other troubleshooting steps I can take to improve performance for my website?

For several months, Firefox has been unable to play videos from various different websites, including Netflix, Paramount Plus, Youtube, and others. I've turn off VPNS, reset my internet router countless times, cleared cache/cookies, flushed DNS, updated firefox, updated my video drivers, updated windows, disabled extensions (including adblock), opened Firefox in safemode, and reset hardware acceleration. This is not an issue on chrome or edge. Some of the error messages include: Netflix F7351, Paramount Plus 5000, and error code 102630. Youtube mostly doesn't work on livestreams, and says that my browser isn't compatible.

keep getting "Login to server imap.mail.yahoo.com failed." I've tried everything thru Mozilla to change passwords and tried every password possible. It's been 2 weeks no access to my emails thru Thunderbird. I'm at a loss. what can I do to get into my Thunderbird account without dumpig it all to start over?

I've had Thunderbird mail for some years but I haven't been using this computer for about 18 months. (Mac High Sierra). MacBook Pro 17-inch mid 2010 2.66 Ghz Intel core i7. 8 gb memory

I came to open Thunderbird mail today. It was all set up as before. The Yahoo accounts were fine, and Cloud. But when I opened Google it gave me: "Authorization Error. Error 400: invalid_request You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure. You can let the app developer know that this app doesn't comply with one or more Google validation rules."

I went to Google and was able op open google mail fine as a standalone M-Gmail (https://mail.google.com/mail/u/0/#inbox)

How can I incorporate gmail into Thunderbird.?

This has happened to me on several occasions but today I was fed up with it and came here.

I completed an important message in Thunderbird (latest Windows desktop version) and saved the draft so I could read it over with the Darling Bride before sending it. When I opened the draft to go over it with her, the draft literally stopped in the middle of a word - and nothing after that had been saved!

Several carefully-worded paragraphs had simply vanished, even though I saved the draft when the message was complete. WHY is Thunderbird not saving entire messages when I finish them and hit SAVE??? One can imagine my anger and frustration of trying to recall, word for word, what I had written so I can rewrite it (and it's never as good as the original). I like the idea of Thunderbird and not using the big data-mining email apps out there... but this is ridiculous!

Hi,

I've downloaded T-bird on two computers- a windows platform and a mac. It works find on the windows platform, but on the mac, while it appears to have populated from my email account (IMAP) with no issues, the search feature always returns nothing. On the windows computer, it works fine.

If relevant, it's open on both computers at the same time, but that doesn't seem to cause any issues, as they're pulling from a web-based email account.

Any ideas about how to make the search feature work on the mac? I search for words or names that I know are there, but the results are always empty. It's important, and I need to get it up and running quickly.

Thanks in advance!

Hi, I added this https://packages.gentoo.org/packages/added.atom and in Thunderbird I do not see the summary tag data :(

Is it expected?

I have a <something> that creates a daily sunrise and sunset entry time in my diary. It isn't an addon as far as I can see. It's not a prewritten list, but seems to create its entries dynamically when I first look ahead to a date- filling all the days with the correct sunrise and sunset times. The normal reoccurring event options don't appear when I delete one. i.e. doesn't offer me the option to delete all the events. I have no idea what I did to set this up ( it must have seemed a good idea at a time). I can not see any subscription that would account for it. I've checked all my accounts on my devices. Thunderbird/Betterbird on my main PCs and Outlook.com on my iPhone just in case I brought it in to TB that way ( which seems unlikely). Nothing. Clearly something is working away generating new sunrise and sunset times to display in TB. But I can't find any way to kill it off. I must have found a sunrise/sunset app that does this, but I have no idea how or where. Any suggestions. Either where it might be hiding in TB or where I can track it down and look for instructions.

Edit: Is there any kind of logfile that tracks such events being created?

I have a Samsung A14.....using an Android 14 operating system. I have Dark mode on at all times on my phone, however when I go online to any sites, it defaults to white screen. I have tried the settings on the phone and in the Firefox settings but it still shows up in white screen. On my old phone, I can get all websites in dark mode so I know it is possible, can anyone help me?? Thanks

Hi,

I repaired my inbox yesterday. I had many messages still in that inbox but after the repair I only see 5 messages. I looked in the directory my profile points to for my email and can see a large Inbox file - but I also see a very small Inbox.msf file. It is almost like the process of rebuilding is pointing to another Inbox file. See the picture attached.

I even tried to take a previous copy of the Inbox.msf file from a backup (it was 800 kb). I deleted the old Inbox.msf file and replaced with the larger 800 kb file. When I opened Thunderbird, it started to something: "Building summary file for inbox" and about a minute later those same 5 emails show - instead of the full Inbox I would have expected.

Is there anyway I can re-associate the Inbox.msf file process rebuild/repair to the correct Inbox file (the one that is 737 meg in this case)? I sure would like to get my inbox messages back (and file them away i/o leaving them there vulnerable to this kind of problem in the future).

Thanks in advance,

Patrick

Outlook email accounts are duplicating and asking for passwords which are in the password manager. T/B does not accept the entered password. Gmail accounts are also duplicating and adding weird passwords. Just started last week. Probably has something to do with the new Microsoft Authorizarion rules. It is a mess. I have been a lifetimme used if Mozilla and Thunderbird.

I have Windows 11, Firefox yahoo email. I must have clicked somewhere that consolidated all my email to the left in a narrow format. Can't locate where to correct it. Also had no luck attaching a screen shot. Next to the condensed email, is another column that is blank except for the white envelope. Is there a place where I can change the format? Thank you.

Hello: t-bird 115.12.2 esr dev build. W11p laptop. Drag & drop (also paste) for putting a file inline for a msg do not function "any more," this has functionned in earlier versions. I can only attach the file. I have changed config ed settings mail.inline_attachments & mail.inline_attachments.text to true & restarted t-bird, to no effect (no inline). This is for a simple .rtf of 340 bytes (yes, very small). Please advise. Thank you.

I am running Mac Big Sur, 11.7.10. When I am in Firefox version 127.0.2 and I go into any Google search, the tab crashes. It works in private browsing mode and also in other browsers but not in non-private browsing in Firefox. I have tried disabling extensions, add ons, etc. Nothing seems to help. This started happening a few weeks ago with any YouTube page also. How can I fix this? If I can't I will stop using Firefox as I cannot function like this. Please advise!
