Sorry to hear about that. Both symptoms are most likely related to the protected mode feature of the Flash player plugin. It has security benefits, but seems to have compatibility issues on some systems.

You can disable that feature using a new hidden setting:

(A) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(B) In the search box above the list, type or paste flash and pause while the list is filtered

(C) Double-click the dom.ipc.plugins.flash.disable-protected-mode preference to switch its value from false to true.

This might not take effect until all Flash has been unloaded for a few minutes, or you close Firefox.

Before that preference was added, the way to disable protected mode was by creating or editing a settings file. The following pages/posts provide different approaches for that if it turns out to be necessary (if Flash EXE processes continue to show up in the Windows Task Manager, Processes tab, even after changing the Firefox preference):

• Adobe support article under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

• Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209

• Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078 (alternate version of Carm's batch file with a few changes by me: https://onedrive.live.com/?cid=f7d304d92388737d&id=F7D304D9238...)

Flash needs to completely unload from memory (exiting and starting Firefox up again might help) before this takes effect.

Any improvement?

Hi there, So far, it seems like your suggestion is working. Websites using flash and javascript still have an issue loading, but its only 30secs, instead of 30min of stopping scripts.

I can't say that the problem is fully resolved, it will take some time of constant usage before I can tell if this resolved the issue, or acts as a quick fix.

Thanks a lot though! :D

very nice solution .. hope can work for me too .. because i had enough several hours to have this situation ..

Wow batupermata, I'm glad I'm not the only one. Heh, not saying I'm glad you're suffering with Firefox, but I honestly was thinking that there might have been a virus or some sort of worm on my computer, causing the issue.

I will say, it doesn't solve the errors running javascripts on Youtube and other websites. However, this solution has proven to help more than any I've tried, so far.

Hi TajiyaO, are you getting different errors now than you did before, or just less frequent?

for base.js problem .. it seems solved .. but still another problem when payng youtube and seeing histats statistics .. there is problem with "un-responsive plugin" ...
