Firefox Community Forum

I’ve been testing how different browsers handle redirects and external triggers from game-related tools, and I’ve noticed something odd with firefox. When trying to launch certain experiences or apply custom settings from external links, firefox doesn’t always behave the same way as chrome or edge—it sometimes blocks or ignores the flag triggers completely.

for example, I’ve been working with a roblox-related launcher that uses something like a fast flag through bootsrap to customize the client experience. everything works smoothly in edge, but firefox seems to either strip the flags or block the redirect entirely.

is there a setting I should look into that might be interfering with these calls? could enhanced tracking protection or strict HTTPS enforcement be playing a role?

would appreciate some help....

I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

When attempting to login to ssa.gov (probably a redirect to login.gov (?)) I get the following in a new tab (with url https://secure.ssa.gov/RIL/SiView.action)

I have Firefox for Linux Mint v136.0.2

I usually browse with Strict but removed for this website, made now difference :-\

Since 141 update I have constant problems with youtube. Page does not load at all or loads only partially. Icons on sidebar are broken, youtube logo is black. I tried disabling ublock and greasemonkey but it did not help. Refreshing page multiple times and using ctrl+f5 sometimes helps but issue returns often, every few videos/visits. Clearing cookies helps but only for few hours and then issue returns.

Is it related to WebGPU support that was supposed to be added in 141? Can I disable it somehow?

I accidentally refreshed Firefox when I was having problems and didn't realize Refresh meant wiping everything clean. I found another thread about this, but it's 8 years old and things have changed. How do I use the "Old Firefox" folder on my desktop to restore all my bookmarks, history, etc.?

Firefox on my mac has been acting buggy lately. The last time I quit and reopened it, all of my windows and tabs were gone. there is no restore previous session available and the recently closed tabs and windows options are grayed out. How can I restore?

Good evening Mozilla,

Well I am facing an issue, no sound coming from any website like netflix or youtube or prime from mozilla browser.

Could you please fix it for me.

Regards

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

The latest update 141.0 (64-bit) has changed my default save location from g.drive to users//downloads. How do I change it back to g.drive? I use Firefox synced between 2 computers (1 desktop and 1 laptop). I use google drive so that I can access the same information on both devices. I NEED screenshots to be saved in a specific folder in g.drive. How do I do this. Before this update, there was not this issue. Thanks in advance.

I have a fresh installation of xubuntu 24.04, with firefox 135.0. Middle clicking on links now does nothing, whereas earlier it opened the link in a new tab. browser.tabs.opentabfor.middleclick is set to true.

I've found out that you can create custom prompts for the AI sidebar with the configuration `browser.ml.chat.prompts.*`. Usually, this is done with the selection text. However, I'd like to pass the URL instead. I could use `%url%`, but that does not include parameters after `?` and hence does not work for Youtube.

Is there any variable that I can use to pass the full URL including parameters of the URL?

I downloaded Firefox not too long ago to combat the fact the Microsoft Edge wasn't working correctly, but ever since I downloaded Firefox it's been making my computer run really slow on the browser. Things are often slow like scrolling up on and down pages websites like Pinterest, and the text when typing on Google docs takes a moment to show up after I've typed it and not instantly, for example.

I checked my computer's task manager because I recently cleaned the laptop, thinking that something else was causing it to be slow, but it isn't. I don't have many processes open on the computer mainly mandatory things and my browser, since I use my laptop mainly for school work, music, or writing. Firefox opens multiple processes, the highest being 21 at one time, and takes up most of the memory on the laptop. Is this normal? Because it takes 1,094.0 MB and keeps my laptop's memory at 90-91%. If it isn't normal, how can I reduce this as well as the lag on my laptop when Firefox is open?

I attached a photo as well.
