If you've been avoiding Firefox for it's RAM use or lack of a multi-processor architecture, you might want to try version 54, available now.

Firefox hogs less memory and gets a speed bump in its latest update

A previously unknown trick to quickly access 'about:config' keys and values was posted to Ghacks.net:


Further notes: I have checked that this works in SeaMonkey v2.46, too; from the article's comments, I discovered you can even do RegEx, try it... :shock:

    Code:
    about:config?filter=/refer|book|edDB/i

Ghacks.net just posted an excellent overview of different Firefox versions startup times and memory consumption:


    Quote:
    Main findings are that startup time increased significantly from Firefox 20 to Firefox 51, decreased in Firefox 52 to 54, and then fell sharply to the lowest ever value in Firefox 55.
    Quote:
    For memory usage, the findings where equally impressive. Memory usage increased up until Firefox 54, and fell sharply in Firefox 55.

OTOH, not so great news for Firefox from the market share front:

I saw elsewhere that comparison article posted a few days ago. I'm not sure if it was tested with a clean profile so it's hard to say if other addons/settings were affecting performance. I know for my own profile it's literally about twice as fast to render pages and graphics on a fresh profile. Also with the move away from XUL addons entirely soon in v57 and multi-process enabled by default there won't be the same conflicts and speed should be even better in the future... though at the heavy expense of a loss in functionality.

I just tried v56 nightly just to see what it would be like and Firefox eats memory. Roughly around 300-400 MB for an empty tab, while running a mix of legacy addons and WebExtensions (update: problem was due some legacy extensions! disabling them fixed the memory leaks).

I set the multi-process limit (dom.ipc.ProcessCount) from 4 to 1 and there were still at least 3 to 4 processes running...

Chrome has had a headstart with multi-processes and is recently showing memory usage improvements with v59+. While Firefox offers more configurable options, I'm not sure if Firefox can bridge the gap.

It would have been smarter for Mozilla to start a new browser instead of building on top of an existing browser and trying to retrofit it to use Chrome's extensions API.

Something else you need to take heed before upgrading to Firefox 55:


    Quote:
    Firefox 55 is the next release version of the browser; the planned release date is August 8, 2017.

So a user posted the following:

Quote:
I just noticed that when FF Portable is closed it leaves behind a folder in AppData :
C:\Users\XXX\AppData\Roaming\Mozilla\Firefox\Pending Pings

Using v55 btw.

If I delete the Mozilla folder in AppData, run and immediately close FF Portable, that folder is left behind.

I've confirmed this on Win7x86. Since this is probably just a temporary issue, I thought I'd post in forums. I'll post something to the entry and the PA site if it doesn't get resolved in the near-term.

Refreshing your Firefox installation

I don't know what was going wrong but on a recent system reinstall, Firefox was running incredibly slow, even in safe mode, and especially on Github. I tried re-downloading and it worked fine so I began the task of moving over my old files. Exporting and importing bookmarks is super simple, but the website logins and master password requires two files:

Code:
\FirefoxPortable\Data\profile\key3.db
\FirefoxPortable\Data\profile\logins.json


Copy these to the same subfolder of the new Firefox extract. Works great.

I should also note that I haven't had to do this in 7 or 8 years so I don't think it's an issue with either Firefox or PortableApps.

(More info and where I got this data.)
