crashing Firefox v70

[atomGit]

FF v70.0 on Linux SB 1.1.0

not thoroughly tested; SB will crash the browser on different sites than those in the example, but i found this combo to be repeatable 99% or 100% of the time...

1. start FF
2. open: https://github.com/ghacksuserjs/ghacks-user.js/issues/776#issuecomment-546817097
3. middle click the link in the post to open AMO in a new tab and let it finish loading
4. middle click the AMO tab to close it - browser crashes

there's more to it - uMatrix needs to be installed - i tested with uMatrix 1.4.0 (latest) and settings as follows...

• settings tab: all disabled
• my rules tab - everything removed and allowing all: * * * allow
• assets tab: all disabled
• more tab: all default

then follow the sequence in the last post

looks like the same is true if uBlock O is installed (without uMatrix), though i didn't test with uBO default settings

Tried with fresh install of Firefox and SB and could not reproduce. Could you try with new empty profile to see if it's profile specific.

[atomGit]

see 2nd post - you have to have uMatrix installed as well

[atomGit]

no, you're right, i couldn't reproduce on a clean profile - i thought i tested that - i'll have to do more testing

[atomGit]

i'm sure i tested on a clean profile before with only uM and SB but now i can't reproduce, even with my normal prefs.js uM and SB, so i don't know what's going on

ignore it for now and maybe i'll test more later

[atomGit]

yeah, i see another user mentioned the same problem in a review

it may not be limited to SB either - i installed StoragErazor yesterday and FF crashed immediately upon install

i think found the problem firefox 70 go to

about:config

Search for

dom.storage.next_gen

Set the preference to

False

[atomGit]

very nice work - a quick test here seems to confirm

It seems new LocalStorage implementation is buggy and on the road to be disabled in next point release. Until it's disabled/fixed, workaround @wanglai8 suggested it's only solution.
