I always have multiple tabs open in my browser. Previously, I could easily open (and switch between) 20+ tabs (I have 16GB of RAM). Recently, after opening five tabs, the Task Manager shows 10-11GB of RAM (88-90%) in use! How can this be? I cleared the cache and history, but it didn't help. I installed several RAM cleaners, but none freed up the required amount. None of the five programs worked. Where does that 15GB of RAM go when I open Firefox? When will you finally implement something like Google Chrome—they free up RAM for active pages when inactive ones are opened. Maybe it's because I have so many inactive tabs that the RAM is disappearing? But I had just as many tabs before, some of them inactive, and fewer than 20 active ones, so I could easily open another 20. And now I can't even open five new ones. What's happening to the browser?! SOS!

since many weeks, a lot of website don't work any more, sometimes it work in private, sometimes not at all. i have to use chrome, i hate it but after 20years of use of mozilla, i'm ready to change because of this problem, i don't want to waste my time to use 2 navigators, or try 2 every day.

The task name is:

• "Firefox Default Browser Agent 308046B0AF4A39CB"

It runs at 10:07 every day. The command line from task scheduler is:

• C:\Program Files\Mozilla Firefox\default-browser-agent.exe

Command Line Arguments:

• do-task "308046B0AF4A39CB"

It reports that the version of the browser is wrong and that my profile was used with a later version of Firefox. But everything works just fine so how do I fix this error?

How can I control the intensity of dark mode, if its possible? If, not what?

Some website uses different colored font that is absolutely invisible on a dark mode page.

Firefox 147.0.4 (aarch64) "hangs" for 30 seconds to 1 minute when I launch it on my MacBookPro (OS Tahoe.26.3). Itwon't open the simple web page I have Firefox set to open when it launches -- and I can't navigate to any other web pages. When I try to interrupt, I get an Apple spinning beach ball until finally, Firefox opens that first page.

After working with Apple tech support, I have disabled a number of content barrier Extensions in Firefox-- which Apple tech support felt might have been causing this behavior. Nothing works. And I hesitate to run Firefox without some of them.

I tried deleting my Firefox user profile from my computer, but all that did was prevent Firefox from opening at all.

How can I stop this?
