Update — 27.10.1 on Mac OSX 10.6.8
1. Quite a few sites turn up with a much nicer layout than they used to.
2. YouTube: things are not quite as rosy as they seemed at first. Loading single pages (channels or videos) is still rather sluggish (bouts of pizza wheel), so that I'm having to revise my habit of loading 8-10 of them in one shot (—> 1x AF-crash). So far, 2 or 3 pages at a time seem to be a tolerable limit to avoid a crash. Once they're done loading, it's OK to open another 2-3 of them.
3. Similar problem with Amazon's heavy pages (—> 2x AF-crashes), as having to open ten or more tabs at a time is sometimes necessary for price comparison. So right now, as in the case of YouTube, I'm being careful. It's possible that deleting AF's cache each time it quits has an effect here. Also: Amazon has been going through a fit of changes lately, and there's been a glitch on one of the platforms for a few days that kept its main page from finishing loading.
4. These crashes taught me the hard way that things are not as simple as they sounded wrt. the procedure described in
post 734 — locking the file
sessionstore.js in the current profile to keep it from expanding out of control. At this point I'd suggest launching AF only with Pin Tabs and Home Tab open (if any), letting it "breathe" a bit (that is, not doing anything) so that
sessionstore.js has enough time to refresh, then quitting AF, and repeating this sequence a few times before locking the file for good. Another option could be making a clean start with the default
sessionstore.js that gets created by AF when it creates a new profile:
{"windows":[],"selectedWindow":0,"_closedWindows":[],"session":{"state":"stopped","lastUpdate":1553715043452,"startTime":1553715018141,"recentCrashes":0},"scratchpads":[],"browserConsole":false}
(time stamps would be different, of course)
5. A question for other users of
uBlock Origin. Its database
ublock0.sqlite (in the
[current profile]/extension-data folder) got suddenly resized to 34.6Mb from the 47.9Mb it used to fill — without my editing the filter lists. Because it happened in the midst of other adventures, like upgrading AF, cleaning up certificates in KeyChain Access, new version of uB0 that dispenses of the uB0 Updater extension etc. etc., I can't figure out what could have happened (apparently there's no discussion forum dedicated to uB0?)
