It depends. Can you be a bit more specific? What are you trying to do on Ebay that doesn't work? Do you get an error message?
'I load ebay.com, and I get an empty page'
'I click "Buy" and I get this error message: …'
'When I do a search, the browser crashes'
I don't think so. You can re-start the browser (with Add-ons), then go to Tools > Add-ons and disable them one by one to see which one causes the probem. Likely one that blocks something, like an ad blocker or a script blocker.
I restart several time from safe to normal mode. I noticed that
when tenfourfox is in safe mode, Default is disabled (from the
Appearance tab in the add-ons manager). So then when Default is
disabled I can access ebay properly.
TenFourFox has some trouble again with ebay. I customized the
preference and when I went back to open ebay, the page was the same
as before. So I have done some manipulation and I notice that when I
change the history to "TenFourFox will: Never Remember History" in
the privacy preference it is when ebay is not loading correctly.
I'm also experiencing the same issue on another eBay-owned domain. This is caused by the « Tracking protection » of Firefox/TenFourFox (which is enabled by default in private browsing windows — open the console in the web inspector to see that the tracking protection is blocking eBay images (https://i.ebayimg.com/00/s/…)).
After investigating, I found that this is caused by M1656968. This is « normally » fixed in the online database on which the tracking protection is depending (as this commit proves it) but the problem persits in TenFourFox.
I tried to regress this in Firefox. It works on Firefox 49 (on Mac OS X 10.9.5 (emulated)) and it doesn't work in Firefox 48.0.2 (on Mac OS X 10.8.5 (native)).
Unfortunately, I can't determine which « new feature » is causing this (the browser.safebrowsing.provider.mozilla.updateURL has the same format in both version, the declared SAFEBROWSING_ID is also the same (but differs from the TenFourFox one) and changing the reported version (in the URL) doesn't change things).
Olga, can you give me an actual URL that doesn't work (as opposed to the image)? I looked at that bug and it implies gumtree is also affected, but images load fine there and on eBay on this G5. I'm logged into My eBay right now, and all my purchases and current auctions appear correctly with images.
The domain in question is 2ememain.be. I have the same issue on the other domains listed in the previously mentioned commit, such as kijiji.ca, gumtree and eBay itself (tested on some Intel builds and on TenFourFoxG3 FPR26b1 under Rosetta, on a fresh profile, without jit).
Just to be sure: are you testing this in a private browsing window with the tracking protection enabled (« normal » browsing windows aren't affected — please also note that I'm browsing from Europe) ?
I can reproduce it in a private window, but the original poster reported the issue in a regular one, so I think there are two separate concerns to be worked through. The private browsing window issue is #619 and can be followed up there.
I'm pretty sure askanison's issue is #619. Having a look at the left of the address bar in comment #9 screenshot, there's the little shield icon, which suggests tracking protection is just on browser-wide.
I enable it browser-wide as well, but for sites like ebay I just click on the shield and disable it in the pop-up temporarily.
Looking at comment #12, I think "Never remember history" always launch the browser in private mode, so every window is private. If not that.. on macrumors forums there's custom prefs.js available in sticky threads, and some do have privacy.trackingprotection.enabled set to true.
