Fórum da Comunidade de Firefox

Hello,

This morning Firefox stopped loading new tabs, which usually means it is due for an update and restart. On my work computer, updates are managed by my organization, so I cannot prompt it to check for updates directly, but rather can just restart the application and it updates once closed. Today when I closed the window then clicked the shortcut to reopen, it notified me the exe file had been removed and prompted me to open the Windows store and reinstall, which I did. I have no indication as to why it uninstalled. All of my bookmarks and other history appear to have been wiped.

I have been trying on the support site to see if this data is recoverable, but nothing has panned out so far.

I have used Firefox as my primary browser for almost twenty years and frequently encourage friends and family to use it if they don't already. I have never experienced anything like this before. I am hopeful somebody will be able to assist me where reading through support center options hasn't yet, but if this is not resolvable, I'm done- the crash helpfully wiped everything clean, after all.

Any suggestions or response is greatly appreciated. Best, Z

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!

I have a question about deleting a Firefox profile. When I access the profile screen via "about:profiles," I see two profiles: "default-release" and "Default User." The "default-release" profile is fine because it displays the message "This is the active profile and cannot be deleted." But is it okay to delete the "Default User" profile? Should I also delete the files in the root directory of the C: drive and the local directory? If I delete the "Default User", will it be deleted as well?

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.

When I open the auto hair generator website in Firefox, the page loads but the main feature does not work. The image does not generate, or the button does nothing when I click it. I tried refreshing the page, clearing cache and cookies, disabling extensions, and restarting Firefox, but the problem is still there. I would like to know how to fix [[this|https://hairaidzone.com/]].

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?

I noticed a wierd popup when opening mozilla. It said "you're always starting mozilla when starting the pc". How and why does an internet browser have to have any information regarding when I boot my PC? What else does mozilla look at outside the browser environment?

If they claim it's needed for performance: Illogical, boot times have nothing to do with the internet browser. If referring to general performance then you can't possibly track and tailor every new piece of hardware that enters the market. Instead you make your browser with prerequisites that you yourself control (eg. install vcredist for this browser to work or something like that).

Why then is Mozilla monitoring my computer when the browser isn't even open or running?

I've tryed all obvious instructions and my bookmarks toolbar will not sync
