Make sure the following options are off:
Disable pre-fetching
Rationale: Not doing this will significantly slow down navigation, as Firefox won't prefetch any content before clicking.
https://addons.mozilla.org/en-US/firefox/addon/jslibcache/
Make sure the following options are on:
Allow header modification
Rationale: Otherwise many Javascript libraries won't be fetched from local storage - as they have parameters on their URLs in the HTML code. This isn't going to break any website.`
Make sure to copy the uBlock rules provided, to your uBlock settings, to avoid uBlock interfering:
- Go to the
uBlock rules - copy them
- Open uBlock's
Dashboard - Go to the
My rulestab - Paste them & hit
Save, thenCommit
https://addons.mozilla.org/en-US/firefox/addon/cache-longer/
Set and forget.
Rationale: Increases the time items will be stored in the browser cache. This increasing the chance that network ressources won't need to be fetched. As NVMe/SSD storage is cheap and lightning fast compared to network requests, this has the potential to improve load times significantly.
- Go to about:preferences#privacy
- Select
Custom - deactivate all filters in this section
- Scroll down to
Security->Deceptive Content and Dangerous Software Protection - Disable
Block dangerous and deceptive content
Rationale: Those filters use a lot of CPU time to process, and are not very helpful - except for newbies. The Dangerous Software filters may actually even block downloads the user want to fetch, that's why it is recommended to disable these.

Rationale: By default Firefox launches as many processes as you got CPU cores. This is highly counter productive, as this leads to much more memory usage as necessary. In addition switching tabs may now result not only in having to load the content back from the swap into memory, but also swapped in duplicated libraries etc.
- Restart firefox
Go to about:support then scroll down to "Places Database" and select "Verify Integrity". This will rewrite the database.
Scroll up again and select "Clear startup cache" on the right side.
- Restart firefox

Configure skip categories to your likings.
- add browser.cache.disk.metadata_memory_limit
- Remove "cache cleaning" from finishing touches (as it's not really necessary and confuses people)
- set layers.acceleration.force-enabled to false (as it may increase CPU usage)
- Remove uBlock Origin's
Disable hyperlink auditingunckecking recommendation (no idea why I've added that) - Organize Settings for Add-Ons under headlines
- Improve explanation of how to apply JSLibCache's uBlock rules
- Add Rationale to some settings, to avoid that people have to google
- Fix
browser.cache.frecency_half_life_hours - Minor changes/fixes to formatting
- Reduce process counter down to one
