Firefox Support Forum

Hello, I have a very odd problem with my firefox browser. I am running firefox 88 64bit on a 16.04 (I know...) Ubuntu. On certain websites, I have an issue with interactive content: www.leboncoin.fr will not let me login anymore (quite recent) www.decathlon.fr will have trouble displaying user comments, images, let alone placing an order Now and then websites with dynamic content and forms will not load...

I am not sure what is the link between all these but it seems related. I have tried the troubleshoot mode but it does not change anything. At the moment when I need to use these king of website I have to switch to another browser.

Thanks in advance for your help!

Please tell me what to do to have the magazine work. It used to, but I think that some new thing like Adblock must have changed it and I cannot read the magazine now. Thanks.

When I open Firefox with a dozen tabs showing, Task Manager typically shows Firefox to be using 1.3% CPU, 715 MB Memory and 0.1 MB/s Disk. However, as soon as I open www.walmart.com in a new tab, Firefox CPU goes up to between 34% to 52%, Memory to 13,900 MB and Disk to 50 to 200 MB/s. If I reboot, it is repeatable. I have an AMD Ryzen 5 3600 with 16 GB. What's going on?

Hello - I've been looking around the Firefox site, and the Internet in general, and so far haven't found out the answer to my question: how do I get Firefox 104 to work on my Linux Mint 18.2 Cinnamon Sonya 32 bit? Specifically what I haven't been able to determine is whether or not I first need to upgrade my Linux, which I suspect. And if so, what's the minimum level of the OS that is required? I may be overlooking the simple answers, but so far I cannot find them. And so far the Firefox website upgrade feature does nothing that I can detect. Thank you for any assistance - Doug.

Hey there,

How can I change the css of pages created by an addon?

(Example-URL: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html)

I know how to change normal pages css via different tools like Stylus etc. (or via userContent.css). But this does not work for pages created by addons.

Can you please help me?

Greetings. How do I set a photo from my pictures library to my FF homepage? I asked this several months ago, figured it out, then lost it again, and can't regain. I'm using v88.0.1, because the update to 90 doesn't work for me, so I assume anything later won't either, if it's built on top of it. Thanks for any relevant responses or suggestions.

on the bookmark pull down menu, the text size and spacing changed considerably from version 88 to 89. has this been changed since? the text was bigger and less space between entries on the rev 88. I have not updated from rev 88 because of this change which is much harder to read in rev 89.

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

I just installed Firefox to my laptop and noticed that Japanese characters are not working. I tried to change the language from english to japanese because I thought it would install the characters but didn't work and rolled back to english. I need to read japanese texts in webpages.... I also checked text decoding from settings > more > text decoding. Unicode is selected and I cannot change to anything else, it is unselectible. What should I do to be able to use the browser properly?
