Just to add, i have found references this problem happening in the past with FireFox. Back then, it was regarded as a bug, which was later fixed. Could this also be a bug? I think its possible.

Thanks Paul.

I have a bookmarklet which activates the yellow message on Facebook. I wait (i.e. don't click either button) and it goes away.

Well the Firefox popup blocker i see (yellow banner across the top, with one button named "Options") does not go away after time. And the bookmarklet activated popup never appears.

This only started with release 85.0 Which updated just the other day. So the problem is with this very latest release. Now seeing this on multiple computers as the update gets applied. So its getting worse.

Can someone look at this, report it as a bug or whatever. The way i understand this is, it should be allowed and not blocked because its coming from a user driven event (button click) and therefor should be trusted. But its not happening.

The setting to block pop up windows is on the Privacy & Security page of Options/Preferences. Alongside the setting is a button labelled 'Exceptions'. Your best course seems to be to add your website as an exception.

Hi Paul, bookmarklets run in the context of the website rather than a privileged context, so they often are subject to the rules of what websites are allowed to do. However, there are some exceptions so it's worth filing a bug report. I may do that; if so, I'll post a link to the report.

Hi terauck. The problem with that as i mentioned before is our bookmarklet works with any site you visit. So it would be impractical to have to allow every site to the exceptions list, its not just our site. The bookmarklet sits on the Toolbar and users click on it, no matter what page they are visiting. This used to work fine, but it changed in v85.

Hi jscher2000, thats great. Thank you very much for taking the time to file a bug report. I will be keeping an eye on that link.

I see another user on redit also mentions this problem. And from what i gather in the bug post, it could well be an actual bug. Fingers crossed it gets resolved.

I'm not that clear how FF rules are being applied to a bookmarklet click (from the Toolbar), but i would have thought it should be allowed?. Having been placed there by the user manually and only clickable by the user, it seems its already passed a privilege check.

Thanks jscher.

The fix has been added to Firefox 86 beta 5, and Firefox 86 should release the week of Feb. 23rd.

Thats great news!. Thank you again for your help. That was very quick.

Paul.

And just to confirm, the issue has now been resolved. Using v86.0 bookmarklets are now working again.

Thanks to all.

Paul.

It's still not working consistently for me in v90 (Mac).

Can you give an example of a non-working bookmarklet?
