Noticed few months ago that some job applications fail to open in Firefox.
After click on job application link, browser just sends me back to https://www.upwork.com/find-work-home/
While everything is fine in IE and Chrome.
Concerning Firefox, also noticed that sometimes common Upwork pages open much slower, comparing to the old site version. And sometimes "Page Kaput" just appears instead.
Did anyone notice such issues?
I use Firefox exclusively and, apart from it being painfully slow at peak US times, I haven't had any other problems.
You could try clearing your browser cache, see if that hekps.
I'm also using Firefox but I don't have any problems with upwork. They usually notify us when they are making an update or something so we can expect problems or lags in those cases.
Have you tried the usual stuff like:
1. Clearing your browser cache and cookies
2. Updating to the latest Firefox version
3. Running Firefox without any add-ons to see if some of them are making the problem (aka Safe Mode)
4. Run a scan with some antivirus or antimalware software to check if some outside source is causing the problem.
