Works as stated and I have been using this for years. However, recently I notice Firefox takes forever to load a page when first launch. In other words, it seems to not connect to the internet for about 2 mins when first launch. After, Firefox works as intended. When this add-on is disable, it loads just fine without issue. This problem happens randomly at startup of Firefox. Currently, Im on Firefox v130.0 x64 but this been happening for a good few versions behind as well. I only now figured out this add-on was causing the issue. I have it disable for about 2 weeks now and I haven't experience the problem at all. Normally I would of had this issue, at least maybe 10 times by now if it was enable.
