Firefox Support Forum

Hello there , I am trying to modify the menu-bar dropdown items when I hover over the list that opens with my mouse ( the dropdown list of any of Help , Tools , Bookmarks , History etc...). It is barely noticeable. I can hardly see the item chosen. I could use some help using the css. I am using FF93 and my platform is win7. Thanks look4

Hi I am trying to change the default homepage Firefox logo to my own, but i could find no tutorial on how to do that. I only found 7-9 year old posts, that did not work. So my question is: Is it possible to change the default firefox logo on the homepage to my own one, and if it is then how?

As of two to three days ago (ca 20/05/22) when navigating to a website (regardless of whether it has been previously visited or not) a message appears stating "PK not found (e1)". I have to click it in order to view the website. Sometimes the message also has a checkbox stating "Allow notifications like this from www.example.com to take you to their tab". I am using the latest FFox 100.0.2 and am fairly sure the problem started after the update before the last one (the last one was this morning 22/05/22).

Hello. I don't know which Firefox release broke this essential feature. The problem started after I enabled Aero in my Windows 7 system. It happens often if I have an open tab with https://www.o2tv.cz/ which uses some DRM to play TV content.

Firefox is my default browser. My email client is Outlook 2010. If I try and view an email in broswer, it comes up using Intenet Explorer. I have tried looking for an .mht reading add-on but nothing seems to exist and existing help info refers to Firefox 58 and doesn't work. Thanks for all help, Jon

I searched extensively for this and could only find answers regarding bookmarks, not add-on icons. Of course I could still be missing it...

I am upgrading from Firefox Developer 86 to 101.

The spacing between add-on icons has been increased in Firefox 101, making the URL bar shorter:

Does anyone know of a userChrome.css script that I can use to decrease the add-on icon spacing in Firefox 101, to make it more like Firefox 86?

I asked this question some time back here: https://support.mozilla.org/en-US/questions/1362859 I'm asking again to reframe the question. The problem is - if my experience is a guide to the rest of the world - VTT files (which are used to caption HTML video) are no longer read/loaded by Firefox when it is viewing the HTML file locally (i.e. file://). On the web they are loaded as expected. Presumably there's a security setting somewhere in Firefox that now refuses to load the VTTs locally. Maybe under Help > More troubleshooting information there is a setting to change to fix that?

Random videos will not load following 100.0.2 install.

These symptoms started @ May 21. (See attached file "Recently installed")

This problem is 100% reproducible at: https://www.reddit.com/r/CatastrophicFailure/

Lenovo Thinkpad x140e Windows 7 (all updates installed) Mozilla 100.2.8174

Scrolling down the Reddit page, videos will auto-play when exposed, and stop when scrolled past.

A video not loading/playing will occur on different posts/videos, but will ALWAYS occur. Once this occurs some previously exposed / played videos, when scrolling up, will play when exposed again, and some will not.

This will also randomly occur on Youtube (also observed on Twitter a few times) when multiple tabs are open. Sometimes closing other open tabs corrects the problem. Other times closing Firefox and relaunching is required and is 100% effective.

I have additional diag data / Inspector log files and page source if needed.

Thank you in advance for your help and consideration. - LudditePro
