This just started after Windows 10 update KB4551762 installed. Firefox 75 still browses OK, but will not download any application installer files. Another Firefox-based browser (Palemoon) suddenly has the same problem. Non-Mozilla browsers (Opera/Chrome) continue to download application installers OK from the web. Tried refreshing and reinstalling Firefox 75, but that does not fix the problem. I suspect the Windows 10 update rather than Firefox, because the latest Firefox in a Linux system works OK.

What is going on with using YouTube on Firefox? All of a sudden, the last few days, I keep getting a yellow bar saying that there is a error with Script, Then I find out that the current Firefox does not use Java Script.

This is very annoying, I've and tired of getting this error message every time I open or close a YouTube video. I would prefer that I be able to watch YouTube on Firefox, but I will not watch it much longer if this is what I have to put up with.

I think that if you don't want to allow Java than you provide a platform that with run YouTube without issue. I've used Firefox for sense the early 90s and you are well know for making changes that don't provide a user friendly environment every now and again. If you can't provide a error free means of watching YouTube, I will be looking for a Browser that does. Even though I hate being tracked by Google. I am sure they track my us of YouTube but at least I don't have to put up with poor viewing or have a video interrupted because of Java Script not being used.

How can I change the sizes of fonts and icons in the Menu and Toolbars?

I'm using Firefox 67.0 under MX Linux. My monitor is 25" with a resolution of 1920x1200. With this resolution, the text and icons in Firefox Menu and Toolbars are tiny and almost impossible to read. The Thunderbird add-on Theme and Font Size Changer works reasonably well for Thunderbird, so is there a corresponding add-on for Firefox?

I know that Firefox is largely developed by people who are volunteers, but it seems that a tool, as part of the basic Firefox program, should be available to make these changes without installing add-ons or modifying the code manually. Almost everyone needs to be able to tweak these things at one time or another.

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

After changing the size of the paging file, the browser began to absorb all the available memory and crash itself and other applications

win 7 x64, 65.0.1 I changed the paging file from a dynamic value to a fixed one (twice as much RAM), after which firefox spontaneously began to absorb all the RAM, which subsequently led to the crash of firefox itself, and other applications (such as discord, gog galaxy, etc.). This does not happen all the time, I can use the browser for an hour, then the memory will start to disappear, or I can only launch the browser and it will immediately begin to absorb memory. After restarting browser, everything returns to normal and no problems are observed until the computer is restarted. How to fix it all?

The issue seems to be with DRM. Although DRM videos play on other sites like on Amazon Prime Video. I've done everything I could find on the internet as to fix this issue like I've checked and unchcecked play DRM content in the settings and cleared cookies and cache and everything but nothing seems to be fixing the issue. Also, everytime I load Netflix I get a little yellow dialogue box saying installing components please try again. This happens everytime I load Netflix. Now when I click on any video it asks me to install SilverLight, I've installed it already but still it asks me to install it to play the video.

I have to manually shut down the computer to make it stop loading new tabs with the phone number. When I re-start I need to close all the tabs it created (last time it was over 60 tabs). I think it is a bug in Firefox, or my version is defective. I have not yet tried to re-install Firefox.

Dear Firefox.

I have to use XP ATM because of other software I have that doesn't like anything else!

Firefox can't play any videos anywhere in ordinary mode. In SAFE mode, it plays YouTube fine but not any streaming vids., it says 'no content with suitable MIME found' - that's probably not TOTALLY the right wording but the MIME part's right and the overall sense of what it's saying is correct. It can't play streaming video even on YouTube in any mode, though! I know it's not Windows XP because Chrome plays it all fine, it's just I don't like Chrome (feels like Big Brother is Watching Me!)

I've got Firefox 52.9.

Can this version play streaming video, or wasn't it ever able to?

Yours puzzledly - I don't understand why starting in SAFE mode makes it able to play any vids. at all. I thought SAFE mode just turned off all plug-ins, yet if I turn off all plug-ins and start it normally it can't play any video. Only in SAFE mode. So SAFE mode must be doing something else apart from turning off plugins - but what!?!?!

Chris.
