Firefox will not open. I tried every single troubleshoot recommendation, and it still won't work. I thought it may be under the "corrupt profile data" troubleshoot article, but when I followed the recommendations to change to a new profile, the profile manager would not open or run on my computer--as if it never existed. I tried downloading a different browser, and as soon as I imported my firefox data, it started misbehaving in the exact same way.

This is getting extremely frustrating. Anybody know what to do?

I have tried nearly everything I have seen suggested so far, but nothing seems to work. Firefox started hanging and lagging randomly a few days ago. When scrolling, hovering over buttons, clicking and typing, there tends to be a half-second or 1 second delay. Youtube videos and other video websites are basically unwatchable because they lag so much.

So far I have tried:

- starting firefox in safemode - resetting firefox - using hardware accelleration and not using hardware acceleration to see if there was any changes. - disabling all plugins and extensions and disabling each one-by-one to see if any took up a lot of memory usage. (Firefox memory usage was sometimes over 400 Mb) - downloading a freeware program called "Firemin" which apparently stops memory leaks when used to launch firefox. (Memory usage went from 350-400 Mb to 4-8 Mb !) This helped slightly when watching youtube videos but not with any other hanging and lagging problems.

I'm currently using Firefox 22.0.

Please if you have any suggestions respond because I do not want to have to resort to using Chrome. I am too used to using firefox and don't want to lose my bookmarks.

Why is my Adobe Flash slow and laggy on Firefox, no matter what I try, but works just fine on IE7?

Whenever I watch anything requiring Adobe Flash (a YouTube vid, an anime episode on Crunchyroll, the latest episode of a show on RoosterTeeth's website, etc) on my Firefox (Version 22), it's horribly laggy and slow, with the picture AND sound lagging and 'skipping', and occasionally for YouTube the image will 'pixellate' and/or the sound quality will nosedive. According to the right-click option, my Firefox uses Flash 11.8. However, watching a vid on my Internet Explorer 7, which uses Flash 10.0, produces no such problems; the picture and sound are excellent. This problem has persisted ever since shortly after I first installed and began using Firefox earlier this year, when I (apparently mistakenly) accepted the offer to update my Firefox's Adobe Flash to Version 11 (it kept giving me "your Flash is outdated" messages that I had to click away to watch a vid, and that annoyed me so I wanted to make it stop).


This problem has been plaguing me for several months, and now that RoosterTeeth no longer supports IE7, I am unable to properly watch their new episodes. I have tried nearly everything - disabling Hardware Acceleration (with Firefox AND with Adobe Flash), having other tabs closed, several Flash updates as they become available since this problem's inception, upgrading my graphics driver, desperate prayer to God (and I'm a fairly secular man), EVERYTHING.


Could someone please tell me what is causing this months-running problem and how I could possibly hope to fix it?

Everywhere I click the cursor appears like I am going to write something. Idk if I did something or something changed but it is kinda annoying. I may not have noticed it doing this before for a long time but today I have been. It appear wherever I click at the start of a line. I have not changed a thing on my Firefox settings for the longest of time. The only thing I had to do recently was reset how I wanted it to search for updates and it even went back to it's setting I had it on before.

So is this a part of Firefox that is just now catching my attention or did something change?

This just started a few months ago. I cannot open a PDF from a search engine with FF (version 22). I click on a link (PDF) and FF opens a blank tab. I have searched Options-Applications-Search for PDF, and nothing comes up. However, in the applications tab, I can see Adobe Reader (default). PDF opens just fine with IE 10 and Google Chrome. I have read through all of the other posts regarding this issue, and I have tried the advice there to no avail. Can someone please help me? Thank you!

Whenever I try to watch any video on youtube, it will not load more than a few seconds at a time. It will stop and stutter and lag for several minutes before it continues to load. This was not the case as little as 3 months ago. I have update flash and my computer and internet speeds have not changed. Even pausing the video and waiting will not usually allow it to load past about 3 to 10 seconds.

Hi there,

I'm trying to clear all of the browsing history from my Firefox but it's not working. The function clears all of my searches and website preferences and passwords bar one or two websites. I've ticked all of the options for clearing history, apart from 'form and search history' as it won't let me tick this box. I also deleted all of my bookmarks, ran a CC cleaner and STILL there's search history when I start to type into the bar at the top. When I go into my history --> show all history having cleared it, it says that there is nothing there...

For example.. when I start to type P in the bar at the top.. UK Parliament immediately comes up. And my bar at the top of the page isn't one of those where you can just automatically search via Google so I don't think its doing that!...

I tried uninstalling and reinstalling Firefox but even so some websites are STILL there! How can I track these websites down and get rid of them?

Thanks for your help!!

I haven't noticed any pattern to what causes it; just that sometimes, Firefox stops responding to key presses of any kind. I know some websites intercept keys that would otherwise control the browser (which is annoying), but when this happens it affects all sites. I've tried pressing all the modifier keys to see if one is being registered as held down; it doesn't help. Quitting Firefox and starting it again seems to fix it when it happens. I've been using Firefox for a while, and only encountered the problem once I installed it on my new Windows 8 PC.

So I have recently bought a new laptop with Windows 8, and I installed Firefox. For the most part it works fine but I have noticed, for some reason, some webpages do not load properly. It looks as if only the HTML of the site has loaded.

Now I can easily fix this by clearing the cache, but only for the same problem to occur a few hours later and this is really annoying me. The problem still happens in safe mode, and other browsers seem to work fine. I have also tried reinstalling but not a full reset.

Here is a link to what Facebook looks like when this happens: http://oi40.tinypic.com/2gwcbxk.jpg

Please could you help me solve this?
