I am having "print" problems in Firefox Profiles that have Print Edit installed since Firefox 45 was released. But I have so damn many extensions installed it is hard to troubleshoot my problem, which is "error messages" and not being able to print. Easier to just open another Profile (with Print Edit installed) and use that Profile where it works; which leads my to think the problem isn't with Print Edit specifically. My advice is to install an older version of Print Edit from here: https://addons.mozilla.org/en-US/firefox/addon/print-edit/versions/ Hopefully that will stop the crashing for you - but '''you will need to turn off updates for that extension in the Addons Manager.''' And email the developer of Print Edit to notify him of your problem with crashing. But be nice, as he is having to cope with fixes related to e10s problems ''(the 16,8 version fix)'' and we don't want to piss him off, and possibly see fixes stop coming - ''IOW, he gives up and walks away from this extension altogether.'' ''I gotta say if that problem of yours is related to using WinXP and not newer versions of Windows. he shouldn't waste his time trying to fix it. Sorry, but I left WinXP behind a little over a year ago for Win7.''
