When I opened the Thunderbird Calendar this morning 99% of information, appointments, meetings, birthdays, etc. are missing. The Monthly view shows one or two events, the rest of the days are blank.

I have my University of FLorida (UF) email downloaded in thunderbird. It is IMAP so whenever i delete something on the UF website it then deletes in Thunderbird and vice-versa. I am now experiencing for the first time in years a few emails missing in Thunderbird, but that are in the UF website. See for example the email below from PC-Progress I received yesterday (5/16th) at 10:28 am. It shows on the website under imbox, but not in Thunderbird. When in Thunderbird I put the PC-progress email in the search box it founds the email (see screenshot below), but when I click on it it goes to the conversation and the email is not there. Any suggestion?

Hi Community. I have used Firefiox for years on Android phones and my Windows devices. Now I have a Chrome tablet I want to use in place of a Windows laptop I cannot get the desktop to show the Menu Bar. Any suggestions?

When I try to search or use Firefox it is extremely slow and I get an error. I used microsoft edge and do not have this issue. I am ready to stop using Firefox and got back to Microsoft Edge.

In a previous thread 5 years ago, it has been asked how the e-mail filters can be backed-up. Back then, the suggestion was to locate the msgFilterRules.dat in the profile folder.

I just created a new user profile in Thunderbird 91.9.0 and I created some new filters, but the file msgFilterRules.dat hasn't appeared in the profile directory. Has the file been changed? Any tips on how to back-up the filters? Using Ubuntu 20.04.

SOLVED: one has to do the following steps:

1. Go to Help>More troubleshooting information>Profile Directory > Open directory 2. Right click, open in Terminal 3. type the command "find . -name 'msgFilterRules.dat'

this will list all the filters, dependent on different e-mail servers

I have an older MacBook Pro with iOs 10.111111... I tried to update myFirefox browser and found out after the fact that it's not supported by the version I have. I cannot Update the iOs without buying a new McBook... Sadly, no $. Can you assist me in procuring a Firefox version or a link to one compatible with iOs 10.11111...??? I love my Mac but I can't stand Safari...

Thanks ever so much...

I recently updated Thunderbird to 101. from a much earlier version, and of course it destroyed all my custom settings. I found most of the addons I had previously were no longer valid. I managed to get a lot of the previous functionality back with settings and other addons, but one still has me stumped. When I bring a message up, I have it set to fully occupy the screen. There are some buttons at the top of the message header I was able to get working, like Reply, Forward, and Delete. But 2 that I use (or use to use) a lot are the Next message, and Previous message buttons. I can't seem to find any way to get them going again. Is there some way to get a link button, or icon for these in the message header?

Suddenly anytime I use youtube or gmail it loads very slow. I have tried flushing dns, reinstalling firefox but no matter what it just hangs and doesn't load. For example I'll click on a youtube video and it will say I'm offline or on gmail if I try to compose an email it says to retry because it breaks.

Hello, I'm using Firefox 100.0.2 (OS: Ubuntu 20.04). It is not possible to manage if/when firefox updates are installed. In the options-section, there are some information about the current version number, however no chance to configure anything update-related. Updates just happens automatically and interrupt current sessions, leading to spontaneous (and surprising) dysfunction of the opened browser. That's very annoying in case of video conferencing, for example, because it is not possible to open any new tab or windows, always the note there "you have to restart firefox now" - in practice, just like a crashing error. And, the suggested restart does not re-open the current opened tabs/URLs!

Furthermore, within some updates, my language settings get lost, so it turns to English language automatically and I always must add my language packet manually again and again. Thats really annoying and maybe completely disruptive for people that are not able to read in English!

Is there any chance to come over this? Otherwise I guess I must leave using firefox as browser, however this would be not the aim I actually follow. Thx!

Hello, my saved passwords from the Firefox browser on my laptop doesn't sync to my android phone, android tablet, or my iPad.

It only seems to be the passwords that aren't syncing. I've tried pairing with the qr code and pairing by signing in with email. My passwords aren't syncing. I've changed browser and auto fill settings on my devices to Firefox. It's still not working. Please help.

My Tbird no longer shows me a "Send" button once I have written a new email or am trying to reply to a received email. I've searched for possible settings regarding this, but have not located any in Tbird's help section. How can I repaid this loss?

Unable to upgrade to Firefox version 100. I click the link in my Firefox email and, there, am prompted to go to the App Store. When I go to the App Store and select “0pen”, nothing happens.

Thank you.

Firefox crashes randomly with no crash report being generated. It seems to have started doing this about a month ago. Nothing in particular seems to trigger it, and all of my software is up to date. It just closes any and all tabs that are open, as if I exited out of the program entirely.
