Firefox Support Forum

Dear all,

Pretty much the same as mentioned here: https://support.mozilla.org/en-US/questions/1299343

The video in that link explains it.

The menu bar keeps appearing/disappearing at a high frequency, randomly - and a key press will stop the glitch for a few seconds - or when firefox is not in focus. Tried cleaning, removing, without pluggins, setting the ui.key.menuAccessKeyFocuses etc etc. Now running the Beta, still same problem. For a while I suspected iCue and Corsair Strafe keyboard - or USB settings, ports, but nothing obvious. Also weird only Firefox suffers from it in that case.

The weird thing is it can go ok for 4-5 hours but then the next day it's back again - once in this state it's unusable.

Any help would be greatly appreciated,

Best,

Alex

I tweaked my Firefox configs to get better font rendering because I hate how "skinny" they are by default on windows. The options changed are:

• gfx.font_rendering.cleartype_params.rendering_mode to 5
• gfx.font_rendering.cleartype_params.force_gdi_classic_for_families to ""
• gfx.font_rendering.cleartype_params.enhanced_contrast to 100
• gfx.font_rendering.cleartype_params.cleartype_level to 100
• gfx.font_rendering.cleartype_params.pixel_structure to 1
• gfx.webrender.quality.force-subpixel-aa-where-possible to true

After the update, the fonts are default again, and no matter how much I change the configs, it doesn't change anything.

I am on a Mac M1 and up to a month ago I was using the latest version of Firefox (regular) and the last few weeks it had this issue and when I switched to Firefox Dev Edition it went away until today.

The issue is defined as when I right click on a link it left clicks and right clicks on the link at the same time. (It loads the page I clicked on and also triggers the context menu)

I have no themes, no extensions.

Anyone have any idea how to fix this? It's not happening in Safari or Chrome (both latest versions) and it took me years to finally migrate to Firefox and would hate to go back.

Thanks in advance!

Using Firefox Developers edition since the update to 109.0b3 (64-bit). The scroll wheel doesn't work, the mouse button I have mapped to the back button no longer works. If I launch Firefox in troubleshooting mode everything goes back to normal and the mouse performs perfectly in troubleshooting mode. Back in normal mode I have tried disabling all three of my extensions and the problem persists. Mouse performs perfectly in every other application. Sounds like a bug, but I can't find anyway to report it. Any ideas? Thanks

So, I'm a designer and UX Designer, and recently I installed Ubuntu and Firefox Developer. If you're a UX Designer you probably know about Figma.

The problem is that Figma uses the Alt key to show the distances between objects. But Firefox activates the Menu Bar every time I press it.

Can I remove the Firefox menu bar Alt shortcut?

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)

In the pre-Webextension days, there was an add-on that allowed one-step install/run of downloaded executables. It worked like this: When the option was selected, the executable was downloaded into a temporary directory, execute it from there, and finally (optionally) delete it.

Now I only do it manually.

Ironically, MS Edge has this functionality built-in (see attachment).

Is there a way to achieve this on FF?

There's a gap between tabs and the window controls in the top right. You can use this space to grab the window when you have a full set of tabs. This functionality breaks when I move the window to my third monitor.

_05: chrome browser network panel after refreshing 5 times domContentLoaded: 328ms

_06: firefox browser network panel after refreshing 5 times domContentLoaded: 1880ms (5.73x slower)

the problem seems from that the request from firefox gets 200 wheras chrome gets 304 unmodified, which explains the huge speed difference in reloading.

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

Hi guys! Currently I'm working on a project which renders video with webGL. The result works on all browsers as expected but not with Firefox vers 109 for Apple Silicon devices (m1, m2) - the video animation is just lagging,it takes cpu usage up to 160% and the video itself is stretched. Comparing to that Chrome takes 22%, Safari 14% of cpu usage. It's just regarding to this devices, it works fine on Microsoft so I think it's a browser bug regarding to osx verision. Could someone pls help me with that or have a look over?

Used to be very practical with add-ons in the toolbar (cf 1st screen), but with the update they are not here anymore (cf 2nd screen). I don't want to click on the extension button for those addons I'm always using, I want to revert to having the buttons in my toolbar !!!!!!!!

PLEASE DO NOT COMMENT TO GO TO CUSTOMIZE TOOLBAR WITHOUT TESTING IT YOUSELF AND INCLUDING A SCREENSHOT !! This does not work, there are no buttons to drag and drop for the addons.

Bought a new windows 11 ASUS laptop. Trying to install an HTML bookmark file from older windows 10 ASUS laptop. When I execute the HTML file import on my new ASUS windows 11 laptop, nothing happens. Even found and removed the "block protection" in the HTML file.

Why am I unable to import a firefox bookmark HTML file?

Thanks for any solutions anyone can provide.

Sling tv streaming warns that other browsers except Chrome, Edge, or Safari may be problematic when using their service. I updated Firefox and then attempted to access Sling, video was fine but no audio or at best audio was intermittent. Both Chrome and Safari are working fine, but I would much rather use Firefox for all my browsing ! Are there any plans to create a fix for this?

I will be to-the-point: Firefox 109.0 has forced the "extensions" icon (a puzzle piece) on my Bookmarks toolbar.

(1) I do not wish for it to appear there (2) I am not given the possibility to remove it from the "Customise toolbar" screen

Please assist.

bold text I can not get any of my addon sto go to the menubar i just refreshed t firefox and when i did i tried going to view and customiz the tool bnar and nothing happens

Several times now when I access my banking site and export data, the exported data is not correct. Sometimes columns are missing or columns are in the wrong order. One time even the display showed missing columns. Another example is when I look up a stock quote, sometimes the numbers from previous days are displayed. Troubleshooting with the site manager we found if I cleared cache and cookies, the problem went away. Everything works for several days, then the problem reappears.

Clearing the cookies is simple enough but then I have to be re-verified on all of the sites that require such and that becomes a real pain. (ie. We are sending you a text, please enter the number to continue)

Google Chrome and Microsoft Edge both work fine with this site. Please don't make me switch but I will if this continues.

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?
