forward/backward search buttons not working in firefox v53

[mausalimi]

hello mr. quicksaver.

starting with firefox v53 there's an issue. steps to reproduce:

• open an empty tab
• type some text in the find bar
• load a site where this test actually appears.

now the find bar shows the number of hits. but the forward/backward search buttons are greyed out.
if i press CTRL-F again the buttons do work again.

thanks for developing cool addons in the past.

I've experienced a similar issue, and it occurs pretty regularly. However, for me, sometimes it shows the number of results, and sometimes it shows 0 results even when there are some. It also has nothing to do with starting on a blank page for me; in fact, I don't think I've ever done that. In my case, it seems more related to just switching tabs. I'll do a search on one tab, switch to another and do a search, switch to another and do a search, and after doing this a few times, give or take, it breaks. As mentioned, Ctrl+F fixes it. I'm using Waterfox 56.1.0x64.

This symptom (forward/backward search buttons not working) is:

• reproducible at https://addons.mozilla.org/addon/up-to-eleven/
• not reproducible at a Wayback Machine capture of the en-US variant of the address, e.g. https://web.archive.org/web/20181020054945/https://addons.mozilla.org/en-US/firefox/addon/up-to-eleven/

From Implementing Content Security Policy - Mozilla Hacks - the Web developer blog (2016-02-16):

The add-ons team recently completed work to enable Content Security Policy (CSP) on addons.mozilla.org (AMO). …

– so I guess that the issue may occur wherever strictness of CSP is in conflict with this feature of FindBar Tweak.

If you set "security.csp.enableStrictDynamic" to false it will work.

Great! Thanks @Imold
