Colors are distorted in MP4 video as you can see in the attached screenshot. The distorted colors impact video on many sites including yourlearning.ibm.com, webex.com, twitter.com, mlb.com, etc. They do not impact youtube.com which displays video correctly. My Firefox version is 68.10.0esr (64-bit) and my OS is RHEL 7.8, kernel version 3.10.0-1127.13.1.el7.x86_64, Gnome Version 3.28.2

I have tried running in safe mode but the issue persists.

How do get Firefox to display MP4 video with correct colors?

I have observed that work offline is possible only when site has been verified which makes it nightmare. If I restart the browser w/o connection any site cannot be verified and, hence, offline does not work!

Please, tell me how to disable verification: 1) in general, and 2) while working offline.

PS: From version 57 if I remember correct, no multi rows, no extra Tool Bar, no Tab Mix Plus, no Session Manager, no automatic download start with DownThemAll!, no work offline, etc. Firefox >= 57 has destroyed the best UI experience!

Hello; There has many issues with Twitter on Firefox. i) Sometimes it simply refuses to run; ii) Sometimes it takes very long minutes to load if at all; ii) Sometimes it quits working after a while and I need to stop Firefox and restart or even run it in Edge before being able to run it again on Firefox. Twitter is the only program that does that, as far as I can tell. Thanks for your help. Frenchy

On a particular website we are developing we have a peculiar problem where CSS styles that we change are not applied at all at first (with a cleared cache of course), but only if we disable and then re-enable any CSS style on the site via the inspector in the developer tools.

And in some cases it looks like some CSS styles are sort of "messed up", i.e. there seem to be margins or paddings applied where they shouldn't be. And these problems go away as soon as you open the developer tools (or the inspector in particular).

Furthermore the inspector shows CSS styles that appear to have other CSS selectors as their content (see attached screenshot to see what I mean). While this looks like the underlying stylesheet has syntax errors: the stylesheet is fine and has been validated with https://jigsaw.w3.org/css-validator/ - so that shouldn't be the issue. Besides it works fine in Chrome and Safari.

I am at a loss how I could debug such an issue as I have never seen anything like it before. This only started to happen with FireFox 79.0 so I am wondering if other people have encountered something like this also.

Using Firefox 79 on Windows 10, all of a sudden I am getting requests to install an add-on identifying itself as slideclocks.com. I did not ask for it and every time I try to cancel by hitting the "Don't Allow" button, other windows pop up. It also seems to generate multiple Firefox windows, once I counted 18 of them. Doing an "end task" from the Task Manager doesn't help; they just pop back up. I tried reinstalling Firefox but the who process just repeated itself. I tried restarting with "firefox -safe" but that didn't seem to help. I also get a cmd window now and then with the same request to install slideclocks.com. Attached is a sample of multiple windows being generated by this add-on. So how can I get rid of it?

Slideclock comes up and (for me) no matter what I do it keeps cycling back and forth and nothing happens except confusion and more confusion. I can't get away from it... It's time vampire. I don't even know what it is.

When I did a search on Google this morning (after Firefox updated), it looks odd. The font is different and hard to read.

Google is the ONLY page that is like this. Gmail, my calendar, etc. are normal.

I opened it in Microsoft Edge just to see how it looked and it was normal so it appears to be a Firefox issue.

Getting attached error when logging into Zendesk. I've been on with their support already.

Steps: Clearing data, private window. Safe Mode. All extensions disabled. Enhanced Privacy disabled. Check other browsers - successful with Midori and Chromium. Check other OS - I have a win10 vm with Firefox and get the same result. Check other zendesk sites - My company's domain + support.zendesk.com

I confirmed with their support that anyone can create an account at support.zendesk.com so I'm hoping someone that knows what they are doing can see what is up with this site.

Hello,

I recently had to re-install Windows 10 due to its corruption caused by a BIOS update. The diagnosis & re-install was done with the help of Microsoft phone support. My Firefox profile was gone, (as was my Thunderbird), but with Microsoft help, a lot of my data was saved in a separate folder. I was able to fix my Thunderbird from profile data on my previous Windows 7 PC, but I am not quite sure how to use the profile data in the separate folder to reconstitute Firefox to the way it was before my OS re-install. I am adding an image of the files in my original Firefox profile folders. I would appreciate help to retrieve my many bookmarks & history. The profile I would like to use is the one dated 5/26/2020. I will provide any additional information if necessary.

Thank you.

When I go to Firefox help under Privacy there is a line at the top saying my browser is being managed by my organization. I DO NOT HAVE AN ORGANIZATION CONNECTED TO THIS COMPUTER!

The link seems to go to Webroot which I do have - but that makes no sense.

I have this issue on several normal commercial sites. Access denied, you don't have permission...

Latest FF release 79.0. Not using VPN, but still happens with VPN/any server. Spectrum.com, Lowes.com to name a couple. The sites work with other browsers, but I simply don't trust any of them. Sometimes, Spectrum.com will load with scripts blocked, but as soon as I temp allow in noscript, the site breaks. I regularly clean out temp files, cookies, etc with a cleaner as well as not saving anything on exit. Caches and such should be sparkling clean.

Ideas? I really hate to purchase things using another browser, but this has persisted for months.

I am using containers, and have made every setting I can think of to keep my log-ins private. Instead, every time I go to ProtonMail I get shown every email login I have used lately, including a gmail login I only use in a gmail container! ProtonMail advise they do not store this data.

The passwords are not stored, thank goodness.

HOW is Firefox saving it? WHERE? This is actually the creepy and intrusive tracking I came to Firefox to get away from - now they seem more like the perpetrator and I have to go right out of my way to protect myself from Firefox itself. Now I guess gmail knows all my protonmail logins.

Any solutions? I hope my tone is not too exasperated, but if there was another browser option out there right now I'd be gone in minutes.

Thank you!

Firefox for Windows 10, I believe the latest version

Every couple of months I will start up my computer and find all my settings have changed and my Firefox add-ons are gone. I was not able to discern why but I made some changes in the configuration and got the text size back to what I wanted. This time it happened none of those configurations changed but I still had changed text size. I refreshed Firefox and found my add-ons immediately were reinstalled even though they were shown to be working when I checked my browser settings. One of the add-ons was Yahoo Mail ad blocker. I have used Yahoo Mail for years. Recently they have tried to make changes in my mail display to where I am being forced to go ad-free and upgrade to a mail subscription. After this most recent challenge to my computer setting, I am beginning to think Yahoo is disabling the Yahoo Ad Mail Blocker to get me to go to their subscription. Either that or Microsoft is challenging me to use their browser. It is like their is a war going on to win the internet. I miss the old Internet. Is there anything that can be done so my settings don't get hijacked?

Firefox is starting automatically after I am restarting my Desktop with www.bing.com as default Home page. But I have selected the default Firefox Home page in options. I have configured the related about:config option but that didn't help .

Hello,

I got the following problem. When I shutdown my PC and let's say have 20+ Tabs open from a study session, after booting again all these tabs are opened when I stat firefox.

In many cases this may be the intended behavior, but I really do not like it. I would like that my Firefox behaves in the following manor:

At any given time, when I open my browser for the first time my default setting is shown. 

At any given time, when I open my browser, no older tabs from a session before should be opened

Thank for help in advance I am aware that this might be the stupidest question ever and I have to jump through hoops to make it happen.

Hello,

On my website I have a button to download my book in EPUB format. You can see it here: https://imwithlorac.com/get-the-book/#downloads

In the other browsers the file is downloaded, but in Mozilla it opens directly in the browser and unless you have installed in Mozilla an EPUB reader, a page with the raw file opens which does not make any sense. It's the same with the MOBI format. On the other hand, with the PDF format the PDF book opens because Mozilla can open PDF files. What I want is that it doesn't open, but that it downloads when people click on the link.

Does anyone know how?

Thanks

When i want to open a new tab, or new site, the firefox crash and close. This not occure all the time, it's like this close when is over his limit of something that i don't know how to describe.
