When visiting the above site in the latest version of Firefox Developer the page fails to render. However, when I view the page in Firefox (regular non-developer version) there are warnings regarding the site using an unsupported version of TLS. Here is the warning:

This site uses a deprecated version of TLS that will be disabled in March 2020. Please upgrade to TLS 1.2 or 1.3.

Will Firefox in the future drop support for TLS 1.1 and lower?

Hi, since a while I have the issue, that if I click on a Youtube line on my Win10 PC Firefox trys to open Youtube as a Mobile Version and dies not play the Video. ends up m.youtube.com Any idea? thanks

I want to change my profile picture on Mozilla Support to a different photo, but I can't figure out how to do so. I know that the profile picture is connected to your Firefox account, and it sets your profile photo to your Firefox account photo, but it won't change to my new photo. How do I change my profile photo for my Mozilla Support account?

I've found that input fields will not allow entering a forward slash (/) on Firefox Developer Edition (I am on 77.0b7 64bit at present; Windows 10 64-bit). It has been happening for at least a few weeks now.

This does not happen outside of responsive design mode. This does not happen on regular Firefox (I am on 76.0.1, 64 bit currently) either.

Here is my setup at present. Will provide more if asked!

add-ons: adaware ad block installed. plug-ins: openh264 video codec provided by Cisco systems inc. shockwave flash 32.0r0 widevine content decryption module provided by google inc themes: 'light' is enabled.

Anybody got any thoughts as to what may be going on?

HI I have just updated FF from a very old version to 77.0b8 (64-bit). My favourite bookmarks bar had coloured (like windows) folder icons, now they are black, bland and horrible. I have tried searching for an add on that changes the folder icon colours, but the search brings up far to many bookmark add ons not related. I have tried many different searches but can't get a result. Does anyone know of a mod/add on, or a way to change the Folder icons colour please? Many thanks for reading.

I've just updated FF to version 77 and now I get an animation that occurs on a tab whenever a page is fully loaded in. See the attached image for what I mean.

How do I turn this off? Thanks.

Hi, I'd like to get rid of the status bar at the bottom left corner. I know it goes away and it seems impossible to remove. But is there any way to remove it? I add an image to show what I want to remove. Thanks in advance!

In v76, I was able to stop the URL bar from enlarging by setting browser.urlbar.update1 to false in about:config. In v77, this enlarging URL bar behavior seems permanent. I find this behavior annoying and unnecessary for me. Actually, I think this is just plain dumb. The text does not enlarge, just the URL box. Is there a way that I may be able to disable this behavior, thank you.

The "Site information" drop down on the far left of the address bar is corrupted, showing an infinitely repeating pattern of icons. See attached picture for example.

After Firefox updated today, it no longer brings up my homepage when I launch the browser. Instead, it's just a blank page (not even a default page). Clicking on the homepage takes me to the correct address.

>Properties show "C:\Program Files\Mozilla Firefox\firefox.exe" with no extension.

>I've tried resetting homepage defaults in the options, to no change.

Is there anyway I can get my homepage to show up when I launch the browser?

I just noticed that the EBay image viewing widget fails to respond to mouse clicks with the latest Firefox updates. Lots of javascript errors were noticed (see attached image).

Chrome does not seem to have the issue, but I want to continue to use Firefox for all my browsing as before. Does anyone else see this? Is there a workaround?

After an issue with FF not showing websites properly, I decided to uninstall it according to the instructions mentioned under https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems, section4.

After downloading the latest version and installing that, it was mentioned a new profile was made, but I could import or sync with the old profile to restore settings, passwords, etc.

For some or other reason importing this does not work the way it was supposed to, so I am now stuck with a fresh installation with all previous settings being lost.

Is there a solution, please? Help is appreciated. Thanks

I press F11 to go fullscreen, but it only hides the bookmarks bar, not the searchbar. I also tried the button in the menu to go fullscreen, but encountered the same problem. I closed the browser and tried again, to no avail.

How do I either go back to my old Firefox or retrieve all my saved passwords? It asked for an update, now I have something called Lockwise and I have lost all my passwords

Hello,

I have a question about language options in Firefox. I moved to the Netherlands some time ago but I don't speak Dutch (yet). Most menu items are in Dutch right now, making it really hard to understand.

When I first installed Firefox I removed Dutch from the languages list and the problem was solved, after some time when I updated my browser Dutch got installed again and I can't remove it anymore, remove button is disabled.

English is the fist language selected in the languages list. Is there a way to remove Dutch from Firefox?

OS: Windows 10 OS Language: English

Firefox has been my default browser forever but suddenly has started glitching! It will work for about 10 minutes but then the glitch happens and all of the top of the screen loses its text and turns into black/white color boxes that looks pixelated and the whole program freezes. In the picture posted, the glitching continues down the right side of the screen too. If I quit Firefox, it starts up fine again (with all browsing tabs lost) but then the error will occur again in a short while.

After updating to Firefox 77.0, it no longer store my cookies between sessions.

I have made sure the "Delete cookies and site data when Firefox is closed" is UN-clicked.

I tried deleting the cookies.sqlite file and replace it with an archived cookie.txt file, but Firefox 77.0 no longer converts cookies.txt to cookies.sqlite.

I then tried backing up the cookies.sqlite file after a Firefox session spent signing into various accounts, but it too seems to get cleared out.

What the heck ?
