mozilla firefox not responding slow windows 10

I have now tried setting Firefox back to true, the default value. I can now type into the taskbar search field and the results are immediate, It was previously taking several seconds after pressing each character. I noticed immediately, that the computer generally was very noticeably much quicker. UPDATE: Although my computer was working acceptably with the above = false setting, I installed a Windows 10 update on Thursday KB4343909. (In case anyone is dubious, I have switched the setting back and forth several times over 24 hours and it is totally repeatable)What do you have to type in in order to get to those settings? I was seriously considering complete Windows 10 reinstall too!!!! I'm sure this must have started one or two Firefox Quantum updates ago but it coincided with various other updates at the same time. Flash isn't dead slow again (I use it on a couple of sites) and HD videos don't stutter again. Websites load straight away again instead of seeming to pause multiple times and taking 10+ seconds to complete, switching tabs is instant instead of getting delays, reloads and spinning circles. It is using much less cpu and much less memory. Now getting 115 Mbps in instead of about 30.

Default is true.Īpparently switches to single processor mode, which is better in less high spec systems.ĭifference is absolutely astonishing. It's WIndows 10 Home and I am an administrator so don't know why this makes any difference but maybe it adds some clues?įinally found the solution in Firefox Quantum. Any ideas? Thanks.ĮDIT to add If I start Firefox by 'Run as administrator' I get about 70 Mbps. Is there a reason/solution why Chrome and Firefox seem slow on the laptop? I have a similar setup on my desktop and this gives me 110 Mbps across all 3 browsers. Everything is set for System no proxy details. Have even done a full settings reset in Firefox. I have run firefox in safe mode, switched hardware acceleration options etc, nothing changes.

I then ran the Windows 10 Speedtest app, this also gives 110 Mbps. I then ran the test in Edge (which I don't normally use) and this gives 110 Mbps. I was getting about 30 Mbps download speeds. I then ran in Firefox and also Chrome which I both use. Ran superantispyware, malwarebytes and ccleaner.

After the latest Windows 10 updates, I ensured all drivers are up to data, had clear out, deleted cookies and cache etc. I've been thinking my HP laptop was a bit sluggish lately.
