I have used FF for years, now V82 on W7 starts out fine, but bogs down to point you can not type. I have tried all the fixes noted here without success. Monitoring both Windows Task Manager and FF Task Manager shows nothing unusual when this happens. Internet speed is 100MBS.

Turning off addons, limiting Tabs, clearing history, updating drivers, minimizing background programs, etc., has little or no effect. FF just bogs down, and usually doesn't recover until restarted.

This appears to be particularly noticeable on ebay, but does happen at random on other sites. Where else can I look for a clue to what the problem is?

A month to a few weeks ago Firefox started being laggy when switching tabs; also Facebook and Facebook Messenger; on Board Game Arena and also on Discord desktop app (using Electron/chromium) typing was getting laggy. I thought it might be hardware so I tested the memory with memtest86 but that passed. I also tried safe mode on Firefox but that made no difference.

So I reimaged my HD to a known good copy from December 2019 and then also recently to 2018 and updated to latest version of Windows 10. All seemed well but recently again Firefox has gotten laggy. Even typing in here it occassionally hangs.

I've attached a Firefox Profiler link https://share.firefox.dev/2Zlua5o if that helps with me doing moves on https://boardgamearena.com/ website with each move taking several seconds to do.

I have also the profile with more private information if that helps.

Can anyone help me troubleshoot?

This has now happened after the last two Mac updates. I get the TLS handshake forever until it times out. Occasionally something gets through (like the Mozilla help pages!) Unlike others who have posted this issue, the same problem holds in Chrome and Safari. I have tried various fixes, including a new identity on my Mac, with no success. Last time the issue seemed to spontaneously resolve after a couple of hours and never reappeared until Mac updated again. While all this is happening, my email works fine, my husband's macbook pro (just like mine) works fine, and my iPad works fine. I have left this message on the Mac help forum, too, hoping someone will have some idea of what is happening. OS Mojave 10.14.6

When Firefox updates, it's an extremely frustrating experience. Enough so that I'm about ready to switch over to Chrome (I already use it for work). Every single time, websites suddenly can't load and all my extensions stop working. It's happening now! I'm writing this from Chrome.

I'm frankly not sure when or why websites start loading again, but it seems to take about a day for things to get back to normal. I've tried closing and reopening Firefox, but that doesn't seem to do anything. It just takes time. I have a 2017 MacBook, OS Catalina 10.15.3.

Is this a known issue? I see all kinds of possible solutions when I try and look for some myself, but oftentimes the OP says they didn't work and then people offer other solutions. I'm wondering why this seems to happen, and if there's a suggestion for how to fix it once and for all—I've never had this problem with Chrome.

There is a delay sometimes when I type in the address bar. It only happens when using the address bar, when I use search bars in websites or type in Google Docs there is no delay. I tried opening Firefox on Safe Mode, but the problem persisted. I also tried resetting the all browser.urlbar preferences that I had modified to default, but it still lags.

Our proxy team hasn’t found anything abnormal with proxy configuration and pac file size is also small in kbs.

Hello all,

I am using Windows 10 64-bit. I have Firefox version 66.0.1

Everytime I open Firefox, after about 20-30 seconds, the application hangs. I get the "Not Responding" message in the menu bar, and the cursor pointer changes to a spinning blue circle.

The application hangs usually for up to 2 mins before returning to normal. It then always works perfectly for the rest of the browsing session. I've tried closing in Task Manager and relaunching, but the same thing happens.

Has anyone solved this issue?

Thanks

Hello, I recently moved to Firefox from another browser and I am very pleased with it. My usage is that my computer remains on 24/7 with the browser open. I saw a paragraph in the help docs:

"Firefox's memory usage may increase if it's left open for long periods of time. A workaround for this is to periodically restart Firefox."

However this can be inconvenient when you have several tabs open that are logged in to various sites for work, which also retain state which is not restored when the browser is restarted.

Over a few days the memory "leaking" (?) is mounting up significantly as per attached. In summary:

Pre close - system RAM usage 12.5GB Post close browser - system RAM usage 8.1GB (4.4GB drop!!) Re-open browser with same tabs - system RAM usage 8.7GB (actually 9.0GB after all tab views were accessed and put back into the state they were in before closed)

From this simple test I can see that 12.5GB - 9GB = 3.5GB was hogged by the browser and not actually required.

As a developer I am interested to understand the reason for this memory leaking. Is there anything I can do while the browser is open to free it up? Or cause it to not "leak" in the first place?

Thanks,

Andrew

Hello,

Firefox is very slow connecting to web pages. Everytime I click a link there is a 5-10s loading time (wheel spinning) before the web page starts to load. Once it starts, the page loads very quickly and runs normally. I'm not seeing this issue on internet explorer or chrome. I am on Win10 Enterprise.

I don't recall having this issue on the first install, I think it started in the last month. I tried reinstalling firefox and disabling all add-ins.

Any thoughts on a solution? I love Firefox but I've been forced to switch to Chrome until I resolve this issue :(

Immediatly after upgrading FF to Quantum every click has a 3 to 10 seconds delay until a site finally starts loading. Since I am "working" in the web, that way FF is completly useless. Is there anyone else out there having the same problem? Or someone who had and got it solved?

As Quantum is advertising performance and visual improvements for Windows users, like: "Moved the build infrastructure of Firefox on Windows to the Clang toolchain, bringing important performance gains", I can smell the smoke, where my performance problems could result from..

Unbelievable, but I had to install Chrome in the meantime to be able to work on.

Any help appreciated, Marv.

I have a pervasive problem where downloads of moderately sized files (> 100MB) are very slow in Firefox but fast in Chrome. When I begin downloads the speed is fine at around 4MB/s but it quickly drops down to < 200Kb/s. This happens across multiple websites and when on different WiFi networks. However when I attempt to download these same files using Google Chrome they maintain the initial 4MB/s download speed for the entire duration. I have already tried running Firefox in safe mode and resetting it using the "Refresh Firefox" help page. I am running Ubuntu 18.04.

I've been using Firefox Quantum for over a month now on Ubuntu 18.04. However, the extensions Grammarly and LastPass which I need the most do not work as expected. LastPass does not automatically sign in nor does the overlay interface work. I have to right-click on the extension button everytime and launch lastpass in a separate window to Sign in. Nor do I get a prompt to save the password when I create a user account on a website.

Next, Grammarly fails to work - and when it works, Firefox notifies that this extension is causing slowdowns, why?

Hello, Not sure what is wrong with firefox lately but since 60 release it is not the old good fox. Page loading is stalling, when I go to check my speed with firefox I;m getting high latency: Download speed 94.26 Mbps Upload speed 5.40 Mbps Ping 179 ms

Results from chrome:

Download speed 97.55 Mbps Upload speed 5.48 Mbps Ping 10 ms

I repeated this a few times and every time same results.

Not sure why firefox is stalling on page loading, and why is it giving high ping on speedtest servers. I can not measure speeed on speedtest.net. it is giving all kinds of errors even in safe mode, and when I manage to load it it gives very high ping, but everything is working fine in chrome and edge. I can not use another browser because I;m using firefox for years, switched after mozzila (R.I.P.) SO can you please fix this? I;m open to any suggestions.
