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.
