Unable to use many popular file hosting sites
Hi, I'm unable to use a lot of popular file hosting sites. A lot of them completely lock up my browser. I am using FPR13.1 for G5's. Here is an important site with a small image I uploaded for a test. The page loads initially, but then I go to the free download option and it locks up after that. It's supposed to do a countdown and then have me complete a captcha, but I can't ever get to it. I don't know if it's related to "transferring data from google" in the bottom left corner of the screen or something else. Is there anything that can be done about this? Thanks https://ayefiles.com/s7sy009m55jz/tenfourfox_test_file.png.html

Testing with TFF 14.0b with fresh profile, PowerBook G4 1.67 GHz.
The browser doesn't lock up for me on the countdown, it just counts really slowly. There's clearly some JS that the browser takes unusually long to execute, which keeps running even after the countdown has finished. Possibly related to the rather not family friendly ads displayed on the site. Therefore the Google captcha can't be solved because it times out long before you're able to select images and click Verify.
Safari 5 with LWK on 10.5 counts down normally but is then also unable to complete the 'I'm not a robot' challenge displayed here instead of the image challenge.
Turning on Basic Adblock doesn't make a difference. Turning off Ion makes it even slower. One could try to experiment with adblock filters or NoScript to get rid of the offending JS, but it's really hard to do this when everything's slow, and without breaking the Google captcha at the same time.

BTW I was able to download the test file without a problem (incl. Google capture and countdown) using Firefox 45 ESR (no adblocking) running on Win XP inside VirtualPC emulating a 300 MHz x86, running on that same PowerBook. Which is sad on so many levels.

Chris, I can't test right now since I'm out of town, but does the browser console mention if asm.js gets triggered? That would differ greatly between the x86 and PPC JITs.

Asm.js isn't mentioned.

If I disable baseline and ion altogether, it runs a lot faster, about as fast as in Safari. Not stellar, but good enough, no beachballs. The browser is now fast enough to also get the 'I'm not a robot' challenge, like Safari, which it cannot solve, either. (When I choose the useragent to be IE8 I get the image challenge instead and can, finally, proceed to download.) But this aside, the fundamental problem seems to be that TenFourFox's jit may be doing something rather counterproductive in this case.
