Add-ons/extensions can affect your browsing experience by causing your computer to stop responding. Most add-ons require your permission before they are installed, however, some may be installed without your knowledge if the add-on was part of another program.
Because of this, you may want to disable all add-ons/extensions to see if that solves any problems you are experiencing with the Photobucket site.
The steps to do this are different for each browser:
Privacy Browser Extensions:
Extensions like Ghostery and Privacy Badger can cause issues with the functionality of the site. These extensions block pop-up advertisements and block various trackers from collecting data and we cannot guarantee compatibility with these extensions enabled.
If you have an ad blocker installed in your browser, you may also want to disable this completely. Ad blockers cause numerous issues with the way the site functions and simply adding Photobucket as an exception does not resolve those issues.
If you use any AVG antivirus software, there may be an extension that was automatically installed onto your browser called "Do Not Track". This could affect your browser's performance. The steps to disable this extension are listed here: AVG Support
