Manage unresponsive XUL extensions

[dapgo]

Operating system: Windows
Browser version: PM 32.x
Installed add-ons: Reminderfox

Sometimes a XUl extension (Reminderfox) gets unresponsive during the sync process, making the browser 99% unresponsive too.

Is there anyway to close only the extension while keeping PM open?
I tried to kill XUL threads but the browser got closed too?
Can the priority of a extension get reduced so an issue or bad performance don't impact on the browser?

Extensions operate at the same level of the browser, meaning that once installed the two things are basically the same and there is no visible separation.
The best course of action is identifying the issue within the extension and fix it.

And is there any possibility to modify Palemoon to have more control over the XUL engine or the execution of extensions?

If it was not done time ago, probably there are technical reasons to don't do but I am curious about it.

For something like ReminderFox, I think you could actually install the extension into a different XUL application so it doesn't bog down Pale Moon. Since it doesn't really need to modify web page documents within Pale Moon to work, all you need is something that will make the ReminderFox window appear so it can do things. Just leave the other XUL application running in the background and have the ReminderFox window up, that way if ReminderFox crashes again, it takes down the other application and not Pale Moon.

Not sure if this is the kind of solution you wanted, but it is the first workaround that comes to mind...

install the extension into a different XUL application

Since those are rare, here's the easiest way: Create a separate profile and install ReminderFox (and nothing else) on it. While using your main profile, open about:profiles in a new tab and from there you can launch the new profile, which will be a separate browser instance and won't slow down your main one.

To take up athenian200's suggestion about using another XUL application, s/he was much too modest to suggest that you try using ReminderFox in Epyrus, athenian200's email client.

I've used ReminderFox for many years, and it works perfectly in Epyrus (up to and including the latest version), as it did in Thunderbird, FossaMail, etc.

Does ReminderFox rely on any browser-specific feature? I'm thinking of researching a XULRunner revival once I'm done with my application.

What were you trying to sync? Why do you need to use Reminderfox while synchronizing?

Nope. Honestly, it would be a great candidate for XULRunner if that were still a thing.
