Hello, everyone Suddenly Firefox failed to work with google sheets documents. All my work files are unreachable now. Any suggestions what my be the problem and how to fix that?

Thank you for your help!

I usually use Firefox but nowadays when i try to open you tube it displays an error message that the authenticity of the received data could not be verified. It also shows the code PR_CONNECT_RESET_ERROR. i really don't know what to do

I have refreshed my Firefox, because it was slow.

In the description was written: Firefox will save these items:

   Bookmarks
   Browsing and download history
   Passwords
   Cookies
   Web form auto-fill information
   Personal dictionary 

Ok. It's fine. But after refreshing the Firefox how can I restore these elements?

Please send me a step by step instruction, without referring the webpage, because I have read it and it is not clear for me.

Where is my older profile? Where is my new profile? How can I move the elements from the older profile to the new profile?

Thanks a lot: Mihaly

Since upgrading to Thunderbird 78.6.1 my email accounts that are IMAP are performing very poorly. In particular, every time I select a message Thunderbird re-downloads the entire message from the server. It takes many minutes for Thunderbird to start as it seems to be redownloading all messages in every IMAP account every time. This makes the larger accounts with many messages unusable. It wasn't like this before the last upgrade. Is there some setting I need to change or is this a bug introduced in the latest Thunderbird? Thanks for any guidance.

Hi guys, on my thunderbird postal home page, in the lower right corner, is appeared a red signal about the IMAP storage space. It looks at 97% !!! I've tried to move several messages ( some years) storing them in a Local folders, but I haven't had any reduction in the percentage. What i can do !!!??? Thanks for your help

During class today, Firefox unexpectedly crashed on my Windows 10 PC after downloading a pdf file from my History teacher. Now, when I try to open Firefox, a transparent box quickly appears before disappearing again, not opening Firefox. I have yet to find a solution that has worked.

How is this still a thing? Chrome can open any PDF file correctly. Any PDF file I open in Firefox shows the text as blank spaces, and I get the message "This pdf document might not be displayed correctly". Why? Why do I, with Firefox, need a 3rd party PDF reader? I shouldn't have to. Even Microsoft Edge gets this right.

Back to Chrome, I guess...

Hi - when I create a new folder they are not imediatly displayed in the folder list. There are some older posts from 2014/15 about this but non of the sugestions work. The only option is a restart of thunderbird which is so problematic I would rather move to a new email client if this is not fixed. this is happening in both my hotmail account and my yahoo account so pop/smtp and outlook exchange protocols. Thanks Dave...

When I search using Firefox I keep getting a google pop-up which requires me to agree to google's terms and if I refuse I cannot proceed with my search. If i try to open a new search the google pop-up returns but with out the request to agree to google terms. Firefox is my default search engine. How can I stop this very annoying google pop-up?

Hi Forum Folke,

I keep having issues with Firefox (84.0.2) when trying to make online purchases... the dialog window (PayPal or whatever) that should pop up doesn't. The purchase process stalls because the next step doesn't happen. I have to use Chrome to make the purchase instead. This didn't happen until the last upgrade, now it's a frequent problem. Doesn't happen on all sites or with all vendors, but often enough to be a headache.

Since this is a 64-bit browser, should I be using the 64-bit version of Java, or does it not make any difference? If it does (or might) make a difference, how do I tell FireFox to use the 64-bit version (installed in the programsx86/Java/32-bit directory)?

Thanks for your help!

My boss can open her Google Calendar in Chrome and Edge, but not Firefox. It just sits on a blank page and tries to load, but never does. Nothing more than a blank page and the spinning circle. We have:

Cleared the cache Restarted the browser

I saw someone on Reddit posted they were having the same problem 30 minutes ago (2:45 pm EST). However, my calendar opens find on Firefox on my own computer.

Any ideas/solutions? Possibly related to the upgrade to 84.0.2?

Thanks matt

Hi. My Mozilla Thunderbird mail client in the Sent folder incorrectly assigns the person to whom we send the message. I have the latest version of the program. How can I fix this problem?

After I upgraded Thunderbird to 78, the old mails in the Inbox folder are not display (i cannot read them). I also tried the solution that was stated at https://support.mozilla.org/en-US/questions/1297593, but also with no success. Can anyone help me?

I just got a Pi 4b with 8gb. So I picked up SanDisk MicroSD 64 GB with 170Write.

Loaded the Ubuntu Desktop 20.10. It boots in 30 seconds. Wow...

Printer setup was super easy... Had to add Clementine to Play M4A music from itune files.

Ok... Loaded just fine. Plays Great. The Ubuntu 20.10 comes with Firefox 81.0 browser. My favorite Browser. Went out to my Favorite Anime site to play some video. Animefreak.tv

Error loading player: No playable Sources Found

Well the Video Codec plugin not there. Checked the Add-ons Enabled

 OpenH264 Video Codec provided by Cisco Systems, Inc.

This plugin is automatically installed by Mozilla to comply with the WebRTC specification and to enable WebRTC calls with devices that require the H.264 video codec. Visit https://www.openh264.org/ to view the codec source code and learn more about the implementation.

 ! OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly.

So I installed the new version of Firefox 84.0.2 (64-bit). ok. I am using it now. No Video play back in Firefox on Ubuntu 20.10. Same Problem. I turned on the Allow Automatic updates in firefox openH64 Video Codec. Maybe it will update and install. Well I am not holding my breath. Its to bad, because the Pi 4b is just as fast as my Laptop HP envy running win10.

If you can find a fix. I would be grateful.

Since this morning, Firefox fails to show any pages, this includes options.

Both Chrome and IE render sites without issue.

I have attempted the following: 1) Reboot 2) refresh Firefox 3) remove and install - Without removing any profiles 4) remove firefox, delete profiles, and install

Nothing has worked.
