Firefox Support Forum

Firefox and my I.E. 11 Browsers are both very slow most of the time & getting slower. Firefox is very slow to open, hangs, won't respond for a few seconds, etc. I also see a message at times, right above address bar that reads "Mozilla Firefox (not responding)". I have done a refresh of Firefox, started in safe mode, etc. with no increase in performance. I've also cleaned the S.S.D. (solid state drive) (disk cleanup). Please help!

Hello Guys,

After updating Firefox ESR 60.3.0 to a newer version (doesn't matter which version). It crashes directly after starting Firefox. We are using a Windows 2012R2 RDS (terminal) server

When we remove the newer version of Firefox ESR and reinstall Firefox ESR 60.3.0, it works again!

Details of the crash:

I'd love to hear from you for a solution.

Where can I download Firefox Extended Support Release (ESR 52) for Windows in order to continue using the Session Manager extension? It's extremely important and vital that I am able to restore my historical sessions and also save multiple sessions going forward.

When I try to download it, I can see it will be 60 version instead.

Unfortunately I mistakenly updated my ESR 52 version today without realizing I'd lose that extension. This is very frustrating, so to alleviate the issue, I'd just like to have the older version and stick with it. Thank you.

Hi, my installation of Firefox 52.4.1 ESR is crashing reproducibly when I'm not using Safe Mode on certain sites, like Google Maps and Reddit.

I have created a completely new profile without add-ons and themes, and disabled hardware acceleration. Firefox still crashes on these sites. Only starting Firefox in Safe Mode solves the problem.

The problem only occurs on my tower PC which has a NVIDIA GPU, and not on my Thinkpad. Both are running the exact same Firefox version on Arch Linux with identical add-ons and user profiles. So it may be problem with video acceleration, but as I stated, I disabled HW acceleration. Btw. the problem doesn't occur with Firefox Quantum which I don't want to use until the most important add-ons are ported.

Anybody got an idea?

Hi everyone

I've been struggling with a Firefox (v52.6) sluggishness problem for several months, and since in the meantime I tried all fixes I could find suggested in these pages, I thought to try and seek help in the forums.

Firefox is still usable, but resource-intensive pages (e.g. Facebook, Google Maps) are slow to respond, and often freeze the Firefox window (the no-response mouse cursor) for a few seconds. Meanwhile, the same pages (and the same amount of total load, i.e. open tabs) in Chrome produce normal performance, which suggests the sluggishness is a problem with Firefox rather than a performance issue with my PC, which is of decent specs (8GB RAM, i7 CPU).

Typically, Firefox becomes more sluggish the more it's been without a restart, and the memory resources it uses seem to grow proportionately. However, even when it's only using a few hundreds MB (after a restart), it's still quite sluggish, while Chrome, with a similar amount of memory used, is just fine. Likewise, when after a while the RAM consumed by Firefox/Chrome goes up to >1GB (not sure if this is in itself normal or not!), while Firefox is crawling, Chrome is still fast.

What I tried, which did not fix Firefox's sluggishness (or only did so for a short while):

- disable extensions one by one, and even all at once

- disable all plugins

- start Firefox in safe mode

- ultimately, I used the refresh function, and immediately afterwards Firefox seemed to be as fast as Chrome. I subsequently reinstalled all my addons (which include ABP, Zotero Connector, Classic Theme Restorer, NoScript) and settings. The next day, it seems my joy was shortlived, as Firefox is back to its usual sluggishness.

I would not want to migrate to Chrome unless I really cannot find a fix for this problem. Can anyone suggest more things I can try?

Thanks so much for any help.

Simple. I had Firefox ESR 52.9, along with some add-ons that will not work in 55+.

I thought I had disabled automatic updates. But to my surprise, I got updated to 60.

I don't like what I am seeing. My system has a standard of dark text (preferably black) on light background (normally white, light gray if not active), and you are basically forcing a dark theme even in the daytime, even if gray on black is hard to read, even if my monitor cannot go up to "bright" in a short space/pixel count.

I don't like the ultra-tiny little icons for the new tab page (I do like being able to see more sites; the old one capped at about 54 sites no matter what settings I chose). I don't like the new "hidden menu" that is appropriate for touch screens that doesn't respond to keyboard (control F2 on Mac, alt-space on Windows).

I don't like the look at some of my add-ons have changed to. I don't run a touchscreen tablets, and I don't want my computer to be forced to use a browser that pretends that it is.

I don't like that the new Firefox basically forces pocket on me. I don't like pocket, I don't trust its terms of service/privacy policy, I don't like that Firefox/Mozilla has chosen to basically make it a first-class citizen even though it doesn't put my interests first and foremost. I don't like that Firefox has basically decided to say "whatever Google does, we will follow". I don't like that Firefox/Mozilla has abandoned its view of "what is best for the browser user", and gone to "whatever is best for the website".

Ideally, I would like to have ESR 52.9, as well as ESR 60.X, side-by-side. I would use 52 for 99% of what I do, and only switch to 60 for those sites that simply will not work at all in 52.

Ideally, the only difference would be the display of the websites. They would share the same history, they would share the same set of bookmarks, etc. There would be no loss of data when I move between one and the other.

I have a Time Machine backup. What do I need to do to get the old Firefox back, and prevent it from instantly auto updating back to the new junk? Including my old add-ons.

Hello, i'm experiencing crashes every day when i'm trying to see specific web pages. My latest crash report is

https://crash-stats.mozilla.com/report/index/e9b3b28d-a4bb-4807-9adc-56e382160614

I have made an update to the latest firefox version and to the plug-in of java. Thanks

I'm stuck on an older version of MAC OSX. Not my choice. 10.6.6

I had not upgraded Firefox for some time (version thirty-something), but recently checked the "automatic update" box. I suddenly found myself updated to FF 49 even though that isn't supported on my version. It crashed constantly. After some research I downgraded to 45 ESR, now 45.5.1, but I'm still having multiple crashes daily. 8 so far this AM. Firefox has become absolutely unusable for us.

How do I downgrade further to a stable version?

Regardless of versions, FF seams to "leak" on OSX, and after opening and closing enough windows I have to exit and restart in order to free up memory or performance grinds to a halt.Even that is more frequent under 45 than it was before.

Hello,

I have just completed fresh installations of Mozilla Firefox 60.0.1esr on two different Windows 2008 R2 servers with the same results:

- The installation completes successfully without any errors - Firefox launches and opens the browser tabs without any errors - The browser tabs do not load any content even when 'known good' URLs are entered into the navigation bar - The same 'known good' URLs open and successfully load content when IE is used from the same computers - "Try Safe mode" and "Refresh Firefox" from the "about:support" page do not have any affect

Please help Thanks ____________________________________________________________________________________________________________________________

I used Firefox ESR 24.6.00 before upgrading from Windows XP to Windows 8.1 this summer. It has, and still does, work perfectly...with the exception that Firefox has started nagging me to upgrade.

I stopped upgrading when the Firefox upgrade (latest and greatest at the time) had problems with XP.

I dont know why, but this day my firefox doesnt show the history download, I didnt delete them.

I downloaded FirefoxDownloadsView, and this show the list of my downloads, but firefox doesnt do it. What can I do?

My Firefox is 45.3.0 ESR

For many months now, I think since ESR 52.0 update, Firefox is extremely slow. For example, when reading a wikipedia page it takes up to 2 minutes to get the scroll function to respond and move down the page a few lines. Process explorer shows an extremely large number of page faults >7,000, FF gets increasingly slower when I use it more than 10-15 minutes a day and crashes almost every time I close and restart. The crasing threads are all file access operations. From what I observe, there is a similarity to an issue I had 40 years ago when I wrote a multivariance statistics program using matrix calculations. The first few drafts were slow, taking more than 2 days to complete the calculation on a small test database. After careful analysis of the compiler and runtime system, I was able to find the appropriate order for the FOR-NEXT loops such that I minimized the number of disk accesses. The program then finished the calculation on the test database in less than 2 hours. It seems that something similar has occurred in recent revisions of Firefox. I think someone needs to examine the methods for allocating and using computer memory vs. disk memory being used by programmers.

I run Win7 x 64 Home with IE11 and have also been using a Firefox ESR version for years; I don't remember which version of it I had recently. For the last few days, Firefox had been 'overusing my Cpu' so when an update was announced today, I clicked the "What's New" button. Getting no information in the new tab, I foolishly updated anyway and got darkened tabs and changes to the address bar, things such as moving the reload button. I tried unsuccessfully to revert to an earlier 52.9 version and finally to this 60.0.1 version, but the changes remain. FWIW, I don't remember seeing any versions between those two, Anyway, I assume these changes aren't something normally adjustable in the Options, and don't see well enough to want to search everywhere for a solution. Can anyone shed some light on this matter, specifically explaining how to revert to the earlier format?

Below is a snip of the top of my page and a bit of the desktop on the left, the page showing the darkened tabs.

Hi, some of our users are experiencing crashes. I believe they click on a link appearing on a windows forms app and this causes firefox to crash. This also causes the windows forms app to crash as well. The issue appears to be intermittent. Can we please get some more details and potentially a solution to avoid this in the future?

Example crash id: bp-6143d7c7-4af9-46f4-a70b-11ee90190402

FireFox Quantum 60.6.1esr (64-bit)

We do use Roboform Version 7.9.32.2 as well.

We are facing an issue with Mozilla Firefox when we try to deliver it via Application Virtualisation where the browser tabs continue to crash. We have tried launching this in safe mode and the issue continues. Is there anything else we can do to troubleshoot this issue? or has anyone else experienced this issue?

We are experiencing a second issue where when we try sequencing Firefox with Adobe Flashplayer via AppV, the published application will not show the flash plugin in the firefox options screen. We can see that flashplayer has successfully installed within the AppV package but it seems to be failing to acknowledge the files in the browser. Has anyone experienced anything similar to this?

Thanks
