Hi. I use an extension for text replacement on pages and since Firefox 32 came I can't use it anymore on most pages (the mid to heavy weight ones), because when I use it, Firefox freezes and don't even show a sign that it will return responsive (I could wait for hours but it doesn't respond again), then I have to force close Firefox and restart. I had to downgrade to 31 so I could continue using both this extension and Firefox, since this is the most important I use. I've tested a simple replacing userscript using the substitution list I have to see if this issue is only with this extension, but I've got the same result: not responding. I've tried to use the extension in Firefox 32.0.2 with all extensions disabled except it, but no different result. With this, it's almost sure that the problem is Firefox itself, isn't it?
