Latest firefox update has turned browser to slow and laggy

Posted

Hi,

I had an automatic update install to firefox around 2 weeks ago. Since then it has gone from being the best and fastest browser on my computer to the slowest.

Even just typing this message there is a massive lag between me typing and it appearing on screen. Prior to the update it used to run perfectly. If I try and clear the search bar to type in a new address it can take 5 - 10 seconds or won't do it at all so I end up typing into what's already there! Basically every action I take with keyboard or mouse has a delay attached to it.

I have so far tried to reset Firefox option which has made no difference.

Am running Windows 7 Service Pack 1 with 4 GB of RAM. Over half of hard drive space remaining.Chrome which I also have on my PC is running perfectly normal. If possibly I'd like to carry on using firefox! :-)

Thanks for any help.

ok, thanks martin. nothing in particular is coming to mind there. however two things you could try is to 1. update your graphics driver: http://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows%207%20-%2064 and 2. your plugins: https://www.mozilla.org/plugincheck/

please report if this makes any difference.

hello, can you try to replicate this behaviour when you launch firefox in the built-in safe mode once for testing purposes?

ok, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might help figuring out what is going on...

I'm experiencing the same issue. I'm experiencing similar keyboard input events being very slow to be processed, with FF 33.02 on windows 7. This was also reported independently by other users into https://bugzilla.mozilla.org/show_bug.cgi?id=1077030

I'm experiencing this lag when using the address bar, or using web sites (e.g. google docs) which become unuseable. Not better after starting from a fresh profile, updating all plugins, I tried resetting firefox https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems without more luck.

I thought it could come from by computer, but the problem does not reproduce in chrome or other windows apps, only in FF

The problem is caused by the new "off main thread composition" feature which was enabled in Firefox 33. You can disable this in the Firefox preferences by changing the value of layers.offmainthreadcomposition.enabled to false.

I opened the bug you mentioned two weeks before the release of Firefox 33, but never received any feedback. I even sent an email directly to the developer but didn't receive an answer. It gives the impression, that the developer is not interested in feedback.

Thanks testit. The workaround of disabling "off main thread composition" by changing the value of layers.offmainthreadcomposition.enabled to false, indeed solved my issue.

Sorry to hear your warning to FF developers were not heard and this bug slipped through FF users. I hope this can improve in the future.

Thanks again for sharing this workaround and for trying to prevent the bug to be introduced in FF 33.

@gberche: could you post your troubleshooting information too? maybe this can show some similarities between your set-ups...

in addition please run a scan with adwcleaner and free version of malwarebytes for testing purposes. i have seen a few omtc-releated graphic glitches reported by other users that turned out to be caused by malware (they had other symptoms like you're describing though, so this is just to play safe...)

@gberche, thank you very much! mozilla's enigneers are actively working on the issue. what you could do on your end is to update your graphics drivers through http://support.amd.com/en-us/download/mobile?os=Windows%207%20-%2064 and try it with layers.offmainthreadcomposition.enabled = true again.

@dwarde_2000, your issue looks different. it is probably better if you open a new question about it and shortly describe the symptoms you are having. thank you!

@philipp, my graphics card is an ATI Mobility Radeon HD 5470, running within an acer aspire 5740G with an intel processor.

How is that related to AMD video driver you're suggesting to update?

@gberche: ati has been taken over by amd a while ago. the link provided above is the latest driver available that turns up when you search http://support.amd.com/en-us/download for your configuration.

@philipp thanks for the clarification around ATI and AMD, I had missed that, sorry.

Unfortunately the latest AMD driver are incompatible with my acer model and result into a blue screen of death. I updated to latest acer available ones which were issued in 2009. I confirm the firefox bug still reproduce unless turning explicitly layers.offmainthreadcomposition.enabled = false
